I don't see him winning another Wimbledon. Maybe he will though, I just don't see it happening.
USO he'll definitely win at least one more.
RG I reckon he might get one.
AO he'll win a couple more.
So maybe 11 slams max imo.
helloworld - "If Nadal wants to surpass Pete, he will need 34 slams, twice more than Federer to be in the same conversation with Sampras."
