He said: "We haven't won a trophy for a couple of years now so it would be nice to win the FA Cup and send the boss off with a good end to the season.
"With the squad of players we have got and what's been happening at Chelsea over the last few years I think we owe it to ourselves as a group.
"We owe it to our fans too and to Roman Abramovich.
"He has ploughed an awful lot of money into this football club. With the squad of players we have got, we deserve to be winning trophies."
