Chelsea chairman Bruce Buck cannot guarantee Andre Villas-Boas' future - should they fail to win silverware. Buck has talked about AVB being their 15-year manager.
But when pressed on whether Villas-Boas would be given time as Chelsea boss without winning silverware this season, Buck said: "I'm not saying anything about how we would react if there was a period where we weren't winning trophies, I don't really want to get into that.
"We might win trophies or we might not. A manager needs success to have a long term relationship with a club. Why are we here but to have a successful football club?"
