Granted it would take mammoth effort, but lets say there's still one grand slam, where he can pull it off, which one is the most likely? The reason i bring this up is that, when you look at what Borg, Sampras, Federer and Nadal achieved (aka the only OTHER champions with double digit slam counts in OE!) all four of them had at some point 4 times GS tournament winning streak at their pet slam! Sampras did it 4 in a row at the Wimbledon, Borg won RG 4 times in a row and WC 5 times consecutively, Nadal had two streaks of 4 in a row at RG, one of which extended to 5th consecutive title and Federer won both WC and USO 5 consecutive times! This makes Djoker's 3 consecutive AO titles kinda look shallow and underachieving! It doesn't make a lot of sense and doesn't look right for a player, who had won 15 grand slams! (Partially i blame Wawrinka for that! That damned swiss LOL) So my question is - Do you think that ND still have just about enough time to manage to win one particular grand slam tournament 4 years in a row or that ship has sailed for good? I think objectively speaking for AO and RG (especially RG!) its probably too late at this point, but for WC and especially USO i think it isn't too late, but Novak would have to win either of them this year in my opinion to have realistic chances at extending that streak into third title next year, finishing with 4th in 2021!...What do you think?
