Wimbledon Final; BBC experts on Nadal v Djokovic

The world's top two players Rafael Nadal and Novak Djokovic go head-to-head in the men's singles final at Wimbledon on Sunday. Regardless of the outcome of the match, Djokovic will depose Nadal from the top of the world rankings because of his incredible run of form that has seen him lose just once in 47 matches.
Nadal has gone 20 matches without defeat at Wimbledon and was in awesome form against Andy Murray in their semi-final.
Nadal and Roger Federer have won 21 out of the last 24 majors, but Djokovic's stunning consistency is threatening to disrupt that order, so it is shaping up to be a spectacular encounter on Centre Court.
Here, three-time Wimbledon champion John McEnroe analyses why Novak Djokovic has enjoyed such a spectacular year and Tim Henman looks at the game of Rafael Nadal.
