I think Roger Federer can win Wimbledon without playing his best tennis.
On other surfaces, players like Marat Safin and Rafael Nadal have caught up with him a little bit.
But on grass, Roger's got everything - the weaponry, the movement, the confidence and the two Wimbledon titles already under his belt.
That - and the edge that's he got recently against the top players - says to me that he can win here without playing his best.
His strategy is good, he plays good defence, and anyone who watches tennis knows how good an athlete Roger is.
Last year was one of those phenomenal years when he won three of the four majors. But this year he's not quite playing as well.
He says there's no pressure on him to play well but I think he's got extra pressure because he hasn't won the first two majors.
Of course when you step on the court and you've been playing as great as he has, that virtually guarantees you at least a break each set because you believe in yourself and the other players look at you and feel defenceless.
I think he's going to win a lot more majors but he's got to keep focus because the challengers want to knock him off the mountain.
