Image source, Getty ImagesAston Villa have agreed a £5m fee to sign defender Axel Disasi on loan from Chelsea.
The 26-year-old briefly looked bound for Tottenham but he is understood to have preferred a move to the Midlands club.
There has been no option to buy included in the deal so any fee to make the move permanent in the summer will have to be negotiated at a later date.
It leaves the north Londoners looking for alternative defensive options before the transfer deadline.
Chelsea midfielder Carney Chukwuemeka has joined Borussia Dortmund for the remainder of the season.
The 21-year-old signed from Aston Villa in August 2022 and has made 32 appearances to date, scoring two goals.

Image source, Getty ImagesWe asked for your views on Joao Felix's pending loan move to AC Milan, having only re-joined Chelsea in the summer.
Here are some of your comments:
Keith: Gutted to see him go. He's never been given a chance at this club and he's just been used as a pawn in the club's transfer dealings. It's a real shame he's gone as there are a few players underperforming at the moment.
Chris: Felix has never been given chance, but with Cole Palmer he's not going to. If Palmer gets injured Felix is the player to replace him, so what are Chelsea going to do if that loan goes ahead?
Ken: Felix needs to stop agreeing to transfers to these clubs who horde talent and look for a club that has a real need for him and is a step below. Is he really going to displace Rafael Leao, Christian Pulisic or Tijjani Reijnders at Milan? I highly doubt it.
Kieron: It's a big mistake as Chelsea need him and he's a good player. Enzo Maresca needs to play him more and not keep him as a sub or used only in small games.
Stephen: Felix is a talented player with amazing skills but he has never been given a run in the team to show us how good he is. Yet Nicolas Jackson has been number one forward choice for almost two seasons and remains a player with few skills, no heading ability and is unable to convert easy chances. What Enzo Maresca sees in him nobody really knows. This is a complete mistake and we should have given Felix a chance. Same with Christopher Nkunku as he's not been given a run of games.
Anthony: I personally think the way Felix was used as a pawn in the Conor Gallagher saga with Atletico Madrid shows how awfully Chelsea are being run. We should never have sold Gallagher and then when we signed Felix he was never given a proper chance.

The 22-year-old spent the first half of the season with Super Lig side Goztepe, scoring two goals in nine matches.
Fofana joined the Blues in January 2023 and made four first-team appearances during the remainder of that season.
It is understood the Ivory Coast international has been recalled due to a major knee injury and he is expected to be out until next season.

Image source, Getty ImagesTottenham are back in talks to sign defender Axel Disasi on loan from Chelsea.
Spurs had previously ruled out a move but agents have been working to convince the once reluctant France international to accept the move.
The 26-year-old has struggled under Enzo Maresca this season while Ange Postecoglou admitted to targeting defensive reinforcements after the 2-0 win away at Brentford on Sunday.
Interestingly, Disasi is cup-tied for both the FA Cup and Carabao Cup matches, while Spurs can only register three new players for the Europa League knockout stage.
Disasi could become Spurs's fourth transfer window signing after completed moves for goalkeeper Antonin Kinsky and defender Kevin Danso - with forward Mathys Tel expected to join from Bayern Munich.

The writing may have been on the wall for Joao Felix when he barely celebrated his two goals against Morecambe in the FA Cup third round in early January.
The Portugal international has been 'the man for the small occasions', according to a post match report from the Telegraph.
It highlighted how Felix mostly only starts against lesser opposition in the FA Cup, Carabao Cup and Conference League under manager Enzo Maresca.
It is a strange situation given the attacker once cost £113m when signed by Atletico Madrid in 2018 and was given a seven-year deal just last summer.
Having previously gone on loan to Chelsea and Barcelona, he is looking at his third temporary home to realise the potential he once showed when first breaking through at Benfica.
AC Milan are now close to agreeing a loan deal for the attacker until the end of the season.
What do you make of Felix's impending exit, Blues fans?
A predictable outcome or has he never been given a proper shot in the team?
Watford have signed USA international Caleb Wiley on loan from Chelsea for the rest of the season.
The 20-year-old left-back arrives at Vicarage Road after recovering from a shoulder injury, with the Hornets 12th in the Championship, three points outside the play-off places.
He joined Chelsea from Major League Soccer side Atlanta United but has yet to make his debut for the Blues and spent the first half of the season on loan at French club Strasbourg.

Image source, Getty ImagesTottenham will not be signing Chelsea defender Axel Disasi on deadline day.
The 26-year-old is available on loan and not blocked from choosing his next destination - as long as terms are right, with a loan fee needing to be agreed.
But the north Londoners are not making a move for the Frenchman, which leaves him either with a switch to Aston Villa or staying at Stamford Bridge.

Image source, Getty ImagesChelsea midfielder Carney Chukwuemeka has flown to Germany and is completing his loan move to Dortmund.
The 20-year-old needs to pass a medical but is expected to make the switch before the transfer deadline.
Chukwuemeka is considered surplus to requirements at Stamford Bridge by manager Enzo Maresca and has been encouraged to leave.
Meanwhile, academy defender Somto Boniface is also expected to join Ipswich Town on a permanent deal.

Image source, Getty ImagesChelsea have a lot of potential outgoings in the works today:
Defender Ben Chilwell widely tipped for a move to Crystal Palace;
Defender Axel Disasi is attracting interest from Aston Villa on loan;
Joao Felix also been widely linked with a move to AC Milan. although it appears be agent driven and it is unclear whether Chelsea will accept it;
Fellow forward Christopher Nkunku continues to be linked with Bayern Munich and Manchester United, but BBC Sport's latest contacts have played down the chance of his exit;
One source has explained that midfielder Carney Chukwuemeka has travelled to complete his loan move to Borussia Dortmund;
Marseille are also in talks with defender Aaron Anselmino about a potential loan deal but it could be linked to Disasi's situation;
Meanwhile, academy defender Somto Boniface is expected to join Ipswich on a permanent deal.
The Blues have also been linked with a blockbuster attacking signing, with names including Alejandro Garnacho, Jamie Gittens and Mathys Tel all being linked during the transfer window, but news on incomings has gone quiet.
We asked you what would ensure you are satisfied this deadline day.
Here are some of your comments:
Stevie: We need a keeper and a striker if we want to get into the top four. We will never succeed with Robert Sanchez in goal, and Nicolas Jackson is a back-up striker at best.
Marc: In dreamland I'd say a striker, but realistically I don't think it will be resolved until the summer. Our lack of depth in midfield worries me. As good as Romeo Lavia is, fitness-wise he can't be relied on. If anything happens to Moises Caicedo, we have no replacement. Bring back Lesley Ugochukwu from Southampton. They're down already and I'm sure he'd get better experience back at Stamford bridge.
Mohammed: Recall Djordje Petrovic from loan. Try Christopher Nkunku in the forward line.
Joe: Honestly, I'd just like to see the likes of Ben Chilwell, Carney Chukwuemeka, and Kiernan Dewsbury-Hall get a loan or a deal away, to get them some minutes. They are all good players in their own right but just aren't fitting the mould here. I feel sorry for them.
Nicholas: Too late to do anything. Chelsea should wait until the summer when they can clear out the deadwood. Then they can see where needs strengthening. Also, that gives the current squad an opportunity to settle and play a full season without a huge influx of more players.
Steve: The minimum requirements are to be left with a first XI who have a decent chance of qualifying for next season's Champions League. That means not relying on a Championship goalkeeper and acquiring a striker who knows how to score goals.
It's the last day of the winter transfer window and Premier League clubs have until 23:00 GMT to complete their business.

Former Chelsea manager Graham Potter is back at the Bridge but I don't see it being a happy return for him.
West Ham have actually performed well since Potter replaced Julen Lopetegui, and looked lively, but results have still been mixed.
Chelsea need a new goalkeeper and probably another centre-forward too if they are going to push on but even with what they have, I still think they will be too strong for West Ham.
Sutton's prediction: 2-1
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 Chelsea on deadline day.

Image source, Getty ImagesTorino have announced the signing of midfielder Cesare Casadei from Chelsea on a four-and-a-half-year contract.
Sources close to the deal have told BBC Sport the Blues have received a £12.5m fee for the 22-year-old and there is also a sell-on clause.
After arriving from Serie A side Inter Milan in August 2022, Casadei made 17 appearances for Chelsea, including five in the Conference League and one in the Carabao Cup under Enzo Maresca this season.
He also had loan spells at Reading and Leicester City.

Image source, Getty ImagesMarseille have started talks to sign Chelsea defender Aaron Anselmino on loan.
BBC Sport has been told by sources close to the situation that the 19-year-old is exploring his options for a temporary move before the deadline.
Anselmino was signed from Boca Juniors in the summer but returned on loan until January, when he began training in west London.
He has yet to make a matchday squad under manager Enzo Maresca.
However, slow progress was to be expected as he adapts to a new country, culture and level, while he also arrived with a hamstring problem.
