Mourinho believes Costa will shine

Jose Mourinho thinks new forward Diego Costa is a superb addition to his Chelsea squad, and says the other players have been surprised at how much ability their new teammate possesses.

Costa, 25, impressed for Atletico Madrid last season as they won the title in Spain, and has now joined Chelsea after they met the £32 million ($67.4m) buy-out clause in his contract.

Mourinho (below) told Sky Sports: "He's a great addition for us. He is a fantastic player.

"Technically he is very, very good. That's why lots of players are so happy and so surprised, because his quality is even higher than what they expect.

"He is so strong physically, and he gives so much effort during matches.


"When people see him play, the first thing that gets into their eyes is exactly that - the capacity to work hard for the team, and to be so powerful and so strong physically.

"To have Diego, (Fernando) Torres and (Didier) Drogba as our strikeforce is something that gives us different qualities. We are really strong in that position now."

Chelsea great Drogba is back at the club after two seasons away and, although he is 36 now, Mourinho says the striker still has the attributes needed to be a success in the Premier League.

"The killer instinct is there, the technique to score goals is still there," said the Chelsea manager.

"He is still very strong physically. Mentally, exactly the same.

"Every training exercise, every competitive situation in training, his desire to compete and to win is always there. I think he's an important player for us."

Mourinho also confirmed that Torres will not be sold during this transfer window.

"We have a good squad," Mourinho said. "The perfect squad would be with these 18 players - not 17 or 16 - but rules are rules and we are working hard, even here, for not to have these kind of problems in the future.

"(We want) to have more English players in our squad, which we are going to have in the future, but, in this moment, we are still in the middle of this process.

"So at the moment we have to make a decision about one player not to be on that list."

Asked whether that player was Torres, the 51-year-old was quick to confirm the Spain international would be staying at Stamford Bridge.

"No. Three strikers are fundamental in a squad and we have three strikers; Fernando, Didier and Diego, so one of them is not (going) for sure," he added.

Chelsea have also signed Cesc Fabregas from Barcelona, and Mourinho thinks the former Arsenal man is the complete midfielder.

"I see him as somebody who thinks football faster than the majority of the players," he said.

"He is the kind of player we need in our midfield to bring us to a different dimension.

"The ball possession, the speed of the circulation, the decisive pass. He has everything."
