Image source, Getty ImagesBrighton left-back Valentin Barco has joined Strasbourg on loan until the end of the season.
The 20-year-old joined Albion last January from Boca Juniors and made seven appearances for the club before being loaned to Sevilla in the summer.
However, after featuring just eight teams in the first half of the season he was recalled by the Seagulls.
Head coach Fabian Hurzeler said: "It is important for Valentin to play, and this gives him that chance to get games.
"He had a frustrating time with Sevilla, but this gives him a fresh start and a new opportunity. We wish him well for the second half of the season."
Let's be realistic.
Instead of setting sights high only for dreams to get dashed, we want to know what the minimum requirement is for Brighton on deadline day.
Be as specific as possible and tell us what will ensure you are satisfied come 23:00 GMT on Monday.
Image source, Getty ImagesWe asked for your thoughts after Saturday's Premier League game between Nottingham Forest and Brighton.
Here are some of your comments:
Forest fans
James: What a win. Seven goals, a hat-trick for Wood and a hat-trick of assists for Elanga. Everyone gave 100% and it was the best response to the defeat last week. Nuno has been a breath of fresh air for this club after Steve Cooper. Long may it continue.
Steve: Bouncing back from a 5-0 drubbing is only bettered by the quality throughout this team. We look quality, even after the substitutes. In Matz Sels, we have one of the best keepers in the league.
Fosi: Superb display. The whole XI were totally committed. I was unable to pick out one player above the rest! Please repeat this performance over and over! Superb.
Joshua: We dominated the whole game! An amazing performance, well done. If we keep this up, we are going to give Liverpool a difficult time.
Mark: That's the way to answer a heavy defeat. Real Madrid, look out!
Brighton fans
Robert: An embarrassing performance from start to finish. The lack of fight from these players was the worst thing for me. Hurzeler is getting found out tactically at this level. He is more obsessed with playing a system rather than getting the best out of the players he has to win games. We have more chance of relegation than European football based on this performance.
Keven: Clueless, no vision and slow, telegraphed play. Too many players were too close to each other, leaving plenty of space for Forest to exploit. The manager is struggling to find a style of play that opens up teams. Maybe this is a bridge too far for him at this stage of his career? Is it time for a change?
Fran: The manager got it all wrong. You can't keep changing the team like that. Defensively, we were a shambles. We need to play the same side, barring injuries, every week - just like other teams do. Unless we learn from this, our season is over - if it isn't already.
Ed: Absolutely pathetic. It's like we don't want to win! Why did we start one midfielder against a team sitting third in the league? Shambles.

Image source, Getty ImagesBrighton captain Lewis Dunk has been speaking to TNT Sports about the heavy defeat: "Everything went wrong, it was embarrassing. We let ourselves down. We let the travelling fans down. We let the fans at home down. We have to take it on ourselves. It was us out there that performed like that. We have to look at ourselves in the mirror and bounce back next week.
"I don't think we played with enough intensity or wanted it enough. It's not nice to say as a football player, but we weren't good enough today. As a whole team, we didn't deserve [anything]. It could have been even more [goals].
"We knew that we were coming here for a tough game, they are flying in the league and it is always a tough place to come. That tough? Probably not - and that is on ourselves. We have to work hard now and make sure we don't let ourselves or the fans down like that again.
"It is doing it on the training field, working hard every day and wanting it every day. It starts on the training pitch. Three games ago, we were on top of the world again weren't we, after two wins in a row. Now we are rock bottom again.
"This season has been a rollercoaster. The manager speaks about consistency all the time and that is a prime example of not showing any. We have to work at it. There is a lot of work to do to get to where we want to get to.
"There wasn't much to say [after the game]. We let ourselves down, let the fans down, let him [Fabian Hurzeler] down. There was nothing to say."

Image source, Getty ImagesBrighton boss Fabian Hurzeler has been speaking to BBC Match of the Day about the defeat: "A bad performance, a bad result, I'm very disappointed. I want to see a reaction from the team, but we win together and we lose together. It is also a test, for the individual characters and for the group, to see how we deal with this. Games like this are bad, but maybe it is a signal for us to show a reaction.
"We said we wanted to play with courage. We wanted to play offensively and, in the end, you could say it was a mistake. In the end, we were not good enough.
"You need to have a balance between defence and controlling the ball in possession. We had some big chances and their goalkeeper was amazing. Out of possession, we were not on the field today."
On his five yellow cards in the Premier League: "When we look at the decisions today, they were really poor so I think being emotional is part of it. I know the statistic but, in the end, emotions are part of the game."

Image source, Getty ImagesFabian Hurzeler fielded an attacking team at the City ground, restoring Georginio Rutter and Yankuba Minteh to an XI that also featured Joao Pedro, Danny Welbeck and Kaoru Mitoma – who was the subject of a failed bid from Saudi club Al-Nassr late in the transfer window.
Before the game, Hurzeler said he wanted to "dominate" Forest and there was no shortage of attacking intent from the visitors early on – but those efforts were undermined by a defensive horror show.
Morgan Gibbs-White and Anthony Elanga were given far too much space in the lead-up to Forest's first and third goals of the afternoon, while Gibbs-White also managed to outjump both Welbeck and Tariq Lamptey for the home side's second.
Hurzeler replaced Jack Hinshelwood, Mitoma and Pedro with Matt O'Riley, Simon Adingra and Diego Gomez at the interval, but if Brighton's fans thought things could only get better in the second half, they were wildly mistaken.
Elanga was allowed to dart into the penalty area unchallenged to set up Wood's second, while Lamptey can have few complaints at referee Simon Hooper's decision to point to the spot after dragging Gibbs-White to the floor just a few minutes later.
Verbruggen's stoppage-time clearance into the feet of Jota Silva summed up a truly miserable afternoon for Brighton, who suffered their heaviest league defeat since a 9-0 loss at Middlesbrough on the opening day of the 1958-59 Second Division season.
Image source, Getty ImagesThis was Brighton's heaviest league defeat since a 9-0 loss at Middlesbrough on the opening day of the 1958-59 season.
Lewis Dunk has scored seven own goals in the Premier League, with only Richard Dunne (10) putting through his own net on more occasions in the competition's history.
Since the start of their first Premier League campaign in 2017-18, Brighton have scored more own goals than any other side (19).

I got talking to a Nottingham Forest fan, a lawyer called Mr Gooch, at Birmingham New Street Station on my way back from covering Aston Villa versus Celtic.
He was having a bit of banter with me about how I have suddenly become a Forest fan now they are doing well - so I asked him to give me a prediction for this game.
Mr Gooch has gone for a 2-2 draw, and his reasoning for not backing Forest to win is that Callum Hudson-Odoi is out and he has been a really integral part of their success this season.
To be honest, I am happy to take any help I can here, because Brighton have been so unpredictable this season.
They are a top-half team but their results have been quite up and down, and they have also drawn 10 games, more than any other top-flight side.
Like Mr Gooch, I thought this might end up being another draw. I would have gone for 1-1, but I am going to use his score instead.
He watches Forest every week so he is a proper fan, not someone who has jumped on the bandwagon like myself, so I will listen to him - although I may take legal action if he is wrong.
Sutton's prediction: 2-2
Image source, Getty ImagesEarlier, we asked you to name the former Brighton manager from a series of clues.
The answer was Sami Hyypia, who was in charge of the Seagulls in 2014.
Image source, Getty ImagesBrighton have scored the opening goal in 10 of their 12 Premier League away games this season (including in each of their past five), more than any other side.
Meanwhile, Nottingham Forest have gone 1-0 up in 18 of their 23 league games overall this term, the most in the division.
The average distance of Nottingham Forest's goal-kicks in the Premier League this season has been 43.7 metres, the highest of any side with 121 of those ending in the attacking half, 26 more than any other team.
By contrast, only three sides have taken goal-kicks at a shorter average distance than Brighton this campaign (23.4 metres).
Image source, Getty ImagesWe asked for your views on the news that Brighton had rejected a bid from Al-Nassr for Kaoru Mitoma and what it would take for Albion to sell the winger.
Here are some of your comments:
Peter: He is far too valuable to us to sell him even for £90m which some are saying is the improved offer. We wouldn't be able to replace him so late in the window. I don't get the impression he's money-driven anyway (and his career has not ended yet anyway !)
James: If we want to compete at the top, then we need to ensure we keep hold of high-value players. Money can only go so far. Take Southampton for example. They sold Van Dijk for £75m - look at them now. I'd rather have the quality Mitoma provides than the money.
Jezz: If Brighton sell Mitoma, they're done. It will show a total lack of ambition. Unless he wants to leave - and he's given no indication he does - we should reject all offers. He's our best player, he's also the fans favourite and one of the most popular in the squad. We'd also lose all our support in Japan, which is worth quite a bit in merchandise sales. All in all, it would be worse than letting Yves Bissouma, Moises Caicedo and Alexis Mac Allister go! He's that important. We shouldn't be selling any of our core players to be honest, not if we want to progress.
Nicolas: Selling Mitoma for the right (high) price isn't something I'm completely adverse to. Although we'd all love to hold onto him, no player is bigger than the team. We have so much talent on the wing, and we've seen success without him. We've also seen the impact that large sums of money from transfers can have on the club's dynamic. I'd love him to stay though, great talent and a great guy.
David: Would be sorry to see Mitoma go but for the right price, and I mean in excess of £100 million, then I don't see why we shouldn't cash in. He isn't such an unknown quantity anymore and while we see him shine against tactically naive teams like Manchester United, we have seen him tamed by teams like Brentford and Everton who know to stick two players on him and mark him out of the game. As for going mid season, we have seen Simon Adingra, Yankuba Minteh, Brajan Gruda and Solly March all playing on the wing this season so we have options. He was never likely to end his career with Brighton so now is as good a time as any for him to leave.
Mark: It's not about how much Mitoma is worth - it's about how much Al-Nassr are prepared to pay for him. If they offer Brighton silly money (and 90 million euros is being talked about), the Seagulls will let him go, particularly with Minteh, Adingra and March already on the books and the need for defensive cover more of a priority.
Name this former Brighton manager from the following clues:
I won the Champions League as a player.
Brighton was the first, and so far only, English club that I managed.
My spell in charge of the Seagulls lasted only six months.
Answer will be revealed at 17:00 GMT
