Not every single one. AO 2013, USO 2013, AO 2015 and several times at Bo3 as well. Sure, Wawrinka is the player that beat peak Djokovic the most probably, but to say "every single one" is a massive exaggeration.We don’t have to theorize we watched it several times and Wawrinka won every single one. This isn’t even a debate in my opinion at least not a good one.
I really like Wawrinka, and sure, he has a chance to beat Djokovic if both play their best. With that said, I don't agree that the aggressor always wins if we have two good players in equally good form that use different tactics.Peak aggressor always beats peak pusher, thats how it works and its wonderful to watch.
