I can see Novak winning 2-digit GS counts while Andy collecting 5 at least.
Rafa might add a few more but very unlikely to surpass Roger.
Final tally would be Roger 18, Rafa 14, Novak 12, Andy 6.
“13 GS for a guy who's 27 is incredible. Whatever he's achieved so far is something that everybody should respect, no question about it...” Nole said.
