Ferrero had a 1-2 Grand Slam final record, 0-1 WTF final record, 4-2 Masters final record, and a career high of #1. Del Potro has a 1-0 Grand Slam final record, 0-1 WTF final record, 0-3 Masters final record, and a career high of #4. Please enlighten me how exactly you think Del Potro is a better player.
I don't care about the record man!!!!!!!!!! Look at the era he's playing in?????!!!!!!!!!!!!!!!!!!! LOOK!
Nadal. Greatest ever on clay, he's barely lost 10 times in his entire career on the surface.
Djokovic. Stupid record unbeaten in 2011, with that streak on hardcourts, won everything and didn't just beat his opponents, demolished them.
Federer. The GOAT and an allrounder on every surface.
Ferrero won a slam on his favourite clay without anyone exceptional to get past. He reached the US Open final, again without facing anyone world class. You are comparing stats that are so bloody misleading because the quality and depth of men's tennis during ferrero's time wasn't as good as it is now.
Ferrero was a somewhat world class mover on the slower surfaces with a decent weaponary forehand. He was a good grinder, but chuck him in today's game and he'd barely squeeze the top 10. Del Potro has a thunderous forehand and a thunderous serve, both exceptional and world class shots which we saw completely took apart nadal at shanghai only last month. Ferrero would not get anywhere near nadal or djokovic with his game, or federer or murray. He looked better than he was because of the standard that was around at the time. Big fish in a small pond. All respect to him but there was nothing outstanding about his game and unquestionably overachieved in his career.
