Both.
Yeh he has developed a bit of a chip now but he has reason for it.
I like the way he plays and like the fact he isn't afraid to call out idiotic behaviour.
I'm sure he will play in the majors obviously smarting from an epic match. He'll be better for the experience.
Personally I didn't see too much wrong with the crowd. Sure there were a few numpties there that would call out in between serves, and the umpire tried to control that, but Medvedev let so much of it get to him, that I'm sure it contributed to the loss as impacted his focus.
He seems annoyed that the crowd wasn't supporting him, yet was playing Rafa. If he went into that final assuming the crowd would be pro him rather than Rafa then he needs his head seen to. Add to that, that crowds in finals want the game to go on as long as possible, once it seemed clear that Rafa was on the come back trail in the 3rd, then the crowd got even further behind him. It happens all the time.
I defo get the noises between serves etc, thats not on, but if he thinks people aren't going to celebrate a point for Rafa to win a game or get to a break point etc regardless of whether it was a great shot from Rafa or an unforced error by himself, then again he doesn't understand crowds. They will celebrate both when it is key.
Medvedev is a very good player and will win tournaments but now is the time to decide if he wants to be a crowd favourite (like Rafa / Federer etc) or if he just wants to be respected but not loved like the Joker. His speech on the court was very good, and IMO that was him talking from his heart. Someone in his camp is winding him up about it all, hence the press conference where he came out like a child about school crying to the teacher that the other kids were being mean to him. He needs to grow up and get the mental strength he needs to win a grand slam, if he does that, we will win A LOT of them, he has everything going for him, a terrific serve is a massive weapon, his backhand is dangerous and his net play is very good too. Those jumping backhands are really something to behold though, they are majestic, so strong and so powerful.
