Do you really believe it speaks for him in comparison with Delpo?
Wouldn`t argue with other arguments though.
Yeah. It shows he is always a contender for the slams. Aside from his one win he has also come close on many other ocasions unlike Del Potro.
As for whose win was most impressive, it is close. Beating Nadal/Federer back to back is an amazing achievement. However, considering the circumstances I still give the edge to Murray. After what he had been through in other slam finals and been 2 sets up in this one before getting taken back to 2-2 against someone with Djokovic's reputation for come backs/winning long matches, to do what he did in that 5th set was incredible.
