Cesc Fabregas is expecting big things from Diego Costa at Chelsea this season. The former Atletico Madrid striker struck twice in victory over friendly opponents Real Sociedad last night.
Cesc told Chelsea magazine: "Diego has been progressing a lot in the last two years, especially the last year. He was immense, a real threat in every game.
"He was playing every three days but he was consistently really strong. He goes behind the defence, making the kind of run players like me are really happy with because it gives you an option to play the killer ball. He will do superbly here."
