Bold words indeed! Agreed that muzza is still a work in progress. The other players are improving though or adapting. (Not necessarily Fed. who is going to just miss Murray's peak, I think). Novak can up his game again,showed greatness in his self-belief, comeback & "stickability" at the AO. Rafa will have to work exceptionally hard to come back as he was . I hope he does because it is great for tennis to have 4 such great players playing at the same time. It pushes everyone to be better, just by playing them. There are dangers lurking though & there can always be another new kid in town. Who will step up next?
