The Djokovic "should have never won Wimbledon" line is even tastier when it comes through the tears of little Rafatards such as that brat

Even if his movement is not perfect on the surface, if his serve gets going and he decides to strike his FH, he can be very, very dangerous. He is also willing to come to the net (even if he's not brilliant) and he is, after all, the world #1, so if he plays well, you'd need a very good performance to overcome him. Or be Federer.
As rocketassist pointed out, there doesn't seem to be a clear favourite for SW19 (yet).
