That would be exceptionnal but to be honest i do not think so for many reasons:
1/ grass is his "worst" surface. His last title in Wimbledon is back to 2010. A very long time ago.
2/ the opposition is very challenging with guys like Hurkacz, Berrettini, Roger Alliassime , Shapovalov Cilic and of course Djoko.
3) he finished the last french open with a serious foot injury and he might not be at his full potential.
So, for me, he has very few chances to lift the trophee in two weeks time and as such keep alive his dream to win the four majors in the same year that no one did since Rod Laver back to ...1969.
That will be a very exciting tournament with many potential winners. Tsitsipas and Ruud will struggle and should not reach the quarter finals. I would go for Djoko, Berretini, Hurkacz and Alliassime in the last 4. But who knows? A guy like Cilic, finalist in 2018 against Roger can create a surprise. He is quite fit again and grass fits his huge serve and return skills.
Let's see! We will have fun for sure.
Enjoy the game.
