Brighton 3-0 Chelsea: What Rosenior and Chalobah said

Chelsea boss Liam Rosenior, speaking to Match of the Day: "Nowhere near the levels, not even tactical, tackles, duels, intensity, spirit, energy, passion are all lacking and that is the reason we lost."

On when Chelsea's form dropped: "I have my own ideas, I am not here to make excuses. That was unacceptable from everyone involved with me at the head of it. That needs to change.

"It is accountability. I have defended the players at times when it was the correct thing, but I can't defend that performance. It doesn't represent this football club, it doesn't represent anything I ask from the group and that has to change.

"I feel numb, I'm so angry. I always speak on what I see and that was unacceptable. The goals we conceded were unacceptable and that is something I have to hold my hands up to.

"I will look at the team, will look at individuals and I will look at a team I can trust to do the basics of football, and we should not be talking about the basics of football at this level. It is something we have to adjust very quickly.

"Tonight was not [about] tactical. This was about desire, spirit, courage and I did not see enough of that tonight.

"Nowhere near good enough, and we have to improve that."

Chelsea defender Trevoh Chalobah, asked by Sky Sports whether the defeat by Brighton felt like a big step back: "Yeah, it did. We gave it our all. Just not the best side."

On why the opening 20 minutes were so difficult: "I don't know. We obviously had a gameplan. We tried to execute it."

On whether the gameplan or the execution was the issue: "We tried our best. We worked on it throughout the week. Obviously, we got beat today. We've just got to go again. We can't dwell on these moments, we've got to look forward to the next game."

On Chelsea supporters' frustrations: "We can be accountable. As players, we have to be accountable for the performance. We know how much the fans have been behind us, and we know they are disappointed with the results, not winning at the moment. We just have to stick together and pull through."

On whether Brighton were more on it: "I thought personally that the boys were running their socks off. Everyone in the changing room is tired. It's nothing to do with effort. We gave it our all, we just got beat today."

On statistics showing that Brighton ran more and if his team could've given more: "We ran today. You can say the stats this, the stats that, but I can see the boys are tired, and we ran, so I don't know."

On whether there is pressure on the FA Cup semi-final: "We just have to pick ourselves up. We've got a semi-final to come. It's a massive game at Wembley. Us being at another semi-final, we've got to use that as a positive and try to approach the game with a strong mentality, try to pick ourselves up from this defeat and stay positive."

On whether positivity can be found in the dressing room: "We have to stay positive. Negativity is not going to help. Us being negative, us dwelling on the past is not going to help the situation, so we have to [stay positive]. No matter what happens in life, you have to keep going forward and pick ourselves up."
