It feels like Djokovic does it on purpose. Out of a sudden it becomes clear that he is going to destroy his opponent. When he was 0-2 back, I had a call with a friend and I said Djokovic is going to win it 100%. I know we all love Roger the most, but I believe Djokovic is the best player we have ever seen. That guy is a beast!
I think we have that kind of discussion in the previous days, that somewhat Djokovic takes a dive purposely and then turn himself on like a beast mode, just like what we have witnessed here.
Definitely, Djokovic is the greatest now, and if he can surpassed Roger's number then he will be on top of the list now. But nothing to be ashamed for Tsitsipas, he gave everything, but the mental toughness is the big difference here.
I also just heard that Tsitsipas found out 5 minutes before the game that his grandma died. I don't know how much such an event affects these professionals, but I don't think it helped.
I have no idea who is supposed to stop Djokovic in Wimbledon. I am pretty sure he will tie the number grand slam titles with Nadal and Federer.
