Surely some will break through soon though. I mean Fed kind of came out of nowhere, whereas there's a big bunch of guys we've heard of now waiting to break through. Give it 5 years and I think the landscape of Tennis will begin to change, with Murray winning his last of 8 Grand Slams
Barring injury.....thats about how many i reckon Andy will accumulate..8GS.... Muzza, Djoko and a fit Nadal....nobody will touch them for a good few years...there just isnt anyone anywhere near those 3 when they are on form... The next gen will simply need to wait for these 3 to age out.
