Tottenham boss Andre Villas-Boas admits he needs a favour from Manchester United.
AVB is confident Alex Ferguson can do his men a favour on Sunday by battling against Chelsea despite already winning the title.
He said: "Alex is an extremely competitive manager so I have no doubts about what he does.
"We saw an example of that against Arsenal last weekend and I don't think United will do anything differently against Chelsea, particularly after being knocked out of the FA Cup by them."
