Diego Costa

"I'd say to the fans that you need to be confident that I personally will fight for this club to make sure we are in contention to win as many trophies as possible"

"I'm part of a great group here of players and we will do everything we can to give the fans what they want - and that's titles."

"It’s about the profile of the player and it’s not just about the physical profile or the tactical profile, it’s also the psychological profile."

"I know Diego since he was 17 and he went to Portugal. This is the kind of guy where life was not easy, nobody gave him nothing for free. He has always to fight a lot to do things."

"In Portugal, he was a Braga player and it’s a good team. He had to go on loan to a lower division team to be back to Braga. Then Atlético Madrid bought him, but after that he goes to Celta Vigo because Atlético had Agüero."

"Then he had to go to Rayo Vallecano because Atlético had Falcao. He comes back to Atlético when Falcao goes."

"The guy had to fight a lot to arrive there, I know his psychological profile and I think he is the kind of guy who is afraid of nothing and ready for everything."

"The Premier League is difficult, but he knows and he is ready. To play with the Chelsea responsibilities and pressure, he knows and he is ready too. I don’t think it will be difficult for him to succeed."

"He had lots of possibilities when he moved. It was not just Chelsea, there were other possibilities. A player like him, £30 million for a 25-year-old striker is cheap. He made the decision by himself to come to us — the guy is ready."

"Diego arrived at Chelsea, as he said to me, thanks to his legs and to his heart. He has been given nothing for free. He didn’t go to a big club and get a big chance. He had to fight for everything."
