I can't believe this is coming from Roger Federer, Carlos Alcaraz is twice more dangerous than Rafael Nadal whom you found even difficult to win in your playing days, how then would you find an answer to this whizz Kid Alcaraz?

What are you talking about. Rafael is an exceptional tennis player, and so is Roger. Stop saying bad things about them then act like Carlos is a god. And don't get me wrong Carlos is good too. Just not the level of the big 3 YET

Roger has won multiple grand slams. With the experience and expertise he gained, he is competent enough to analyse anybody's game.

@Mesch, Since you are questioning Roger, how many grand slams did you win? How many atp tournaments did you participate in?
