Diego Costa

"He went to the national team in perfect conditions and came back injured."

"But what happened to Diego happens to many other players in other national teams. I have nothing to say about it. It's just what happens. He played one match and was perfect, then went to the national team, played against France and came back injured."

"Costa has a problem and he can't play in this moment three matches in a week. If he has one week to let the muscle recover, he can start again like he has been since he had that problem with the national team. ‘But three days, after Saturday, is not enough. It was not to protect him for the game for Sunday, but because today he was not in the condition after Saturday."

"He signed for us and was completely fine. He had a problem again in the national team, not with us."

"And now we have a problem and now we have to resolve it as best we can. Today he was not in condition to play. Sunday we believe he is."

"Next week, against Bolton, for sure he isn't. We have to manage the situation until the moment he's completely fine. I don't know (how long that will be). If today he had started the game, for sure he could not play on Sunday. We have to go step by step."

"He is very good. I think for him to start the season in England, coming from Spain, which is a very different league, and to recreate the same thing he was doing at Atletico, is fantastic."

"He’s really good and he’s enjoying playing here and being with us. That’s the best feeling he could have. He’s the striker we needed this season."

"Like me, he came to this level a little bit late. It’s really good. When I look at him, I can see the desire to win every challenge, to score goals. He’s hungry for goals and that’s the best thing for a team like us."

"The whole idea of Diego’s feisty approach is a completely fake point. Maybe it’s a point based upon previous seasons, not what happened here."

"Here he got the right advice, the right education, and yet he got two yellow cards."

"One is completely unfair, because it was a penalty. The second one was because he was provoked for the whole game and he had a little reaction."

"He’s being completely fair, giving zero problems to referees and behaving very well and playing his football."

"The referees are there to see the provocation. Diego is trying to play. He’s not afraid of aggressive opponents. He doesn’t let other players intimidate him."

"I am still carrying some hamstring discomfort, but every day I feel better. The truth is that over the past week I have worked fine."

"I suffered an injury with Spain and could not play against Macedonia (two weeks ago). It was a shame but then during that week I was treated and could play [against Swansea)."

"I'm working to get the best physical condition soon. The games we have now, almost every three days, will help me to get fit."

“I think if he doesn’t go to the national team and stays here 15 days for treatment and recovering, he has the perfect chance to be top for Chelsea and top for the national team.”

“If he doesn’t have this period to put himself in good condition...the muscle is in danger of rupture.”
