FT: Brighton 2-1 Chelsea
Chelsea boss Enzo Maresca told BBC Sport: "We controlled much better the first half. The second half the only shots they had we conceded a goal from.
"I think the handball [before Brighton's second goal] is quite clear. In the last two or three days there were many different moments in different games. Without VAR it's complicated.
"We tried to come here and make our game. We had a few chances at 2-1. Now we can focus on the Premier League and Conference League.
"We always try to win the games. But in the same way you have to take the consequece of the result."
Wlll this affect Friday's game? "I don't think so. Different competition, different game."
FT: Brighton 2-1 Chelsea
Brighton boss Fabian Hurzeler talking to BBC: "Great reaction. We showed character after that start. I'm proud of how they came back. It's not easy. That's why it was well deserved.
"Mistakes happen. If a keeper makes a mistake normally it's a goal. We try to support him because he's a great goalkeeper.
"Georginio Rutter is doing good. He adapted quickly to the intensity of the Premier League. He has great skills and showed it today.
"It was a togetherness on the pitch. It's a team performance. They bounced back, they stuck together. They didn't point fingers after losing. They took ownership."
On no VAR: "But that's it. That's football. With VAR football is getting not that emotional like today. Everyone agrees that today was a great atmosphere. They can celebrate a goal because they know it's a goal. I'm happy it was like that.
"We always try to stay grounded and work hard. We try not to get euphoric after a good win or panic after a defeat.
"That's why we all love football because you can bounce back. It's not always going up, it's downs. In life it's important to know a successful journey is not a comfortable journey."
FT: Brighton 2-1 Chelsea
Brighton have reached the fifth round of the FA Cup in three consecutive seasons for the first time, while Chelsea have failed to progress beyond the fourth round in two of the past three seasons, as many times as in the previous 24 campaigns combined (fourth round eliminations in 2010-11 and 2014-15).

FT: Brighton 2-1 Chelsea
Brighton boss Fabian Hurzeler talking to ITV: "I am really proud of how we bounced back from a big loss. I am proud of how they stuck together.
"It is very important not to overreact to setbacks. I stayed calm. We analysed the reasons.
"We all know what we get from Tariq Lamptey. He is a great team player and put in a very good performance. Mitoma has shown his commitment to this club."

Disaster not having VAR. Why in some rounds of the FA Cup and not others? Leicester were knocked out because of not having VAR in use.

It is a sensational second-half performance from Brighton. They also showed plenty of courage and determination to come back in the first half and they played their game.
They had to defend in numbers and they did that brilliantly. But it's the attacking threat that they have that has impressed me.

I thought being knocked out of the League Cup by Newcastle was our worst performance of the season. Then came Ipswich. Then City. Now this. Maresca is not the way forward.

Diego Gomez tries to wrap it up for Brighton but shoots well wide and in doing so wastes a few more seconds.

Image source, ReutersWe were getting somewhere under Poch, but Chelsea's owners seem determined to suck the personality out of the club. Enzo's football fits in perfectly with that. This is worse than Sarri-ball, whatever that was.

Brighton 2-1 Chelsea
Chelsea's Noni Madueke gets to the byline, but Brighton defend it well. The assistant was flagging, saying the ball had gone out, meaning the follow-up strike, which Bart Verbruggen parried, wouldn't have counted anyway if it had gone in.

Danny Welbeck, who was handed the Brighton club captaincy after Lewis Dunk went off injured, now passes the armband to Adam Webster as the striker is replaced by Matt O'Riley in an attempt to tighten things up and a move to get this one over the line.

Chelsea fans were annoyed with Christopher Nkunku because he was driving forward, with Tyrique George completely open on the left-hand side. He just completely stopped and turned back the other way. It is so disappointing.
If I am George, I am screaming at him to give me the ball. He has not had a touch after coming on.
