Fed only has 20 grand slams. What a loser!

No-one is ever going to question that him, Djokovic and Nadal absolutely dominated this era of tennis. I did consider Federer the GOAT but that surely has to be ceded to Djok now. Nadal I'd find trickier to place, he has more grand slams than Fed but aren't a lot of them in the French? I'm not saying they don't count but implies he dominated on one surface more than others.
