New Chelsea signing Diego Costa has vowed to do his utmost to deliver trophies at Stamford Bridge. The Brazil-born Spain striker joined the Blues from Atletico Madrid and is tasked with scoring goals for which Chelsea forwards have been criticised for a lack-of by boss Jose Mourinho.
Costa told Chelsea TV: "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."
