Good point comparing him to Stan, a lot of similarity.....both have very penetrating power game. Thiem himself said that both at their best, Stanimal has the slightly better backhand...….the highest level of backhand in history, though it's not that level very often. They also have devastating forehand and awesome serves, now Thiem also shows match toughness he is the complete package. Stan at his best also becomes mentally very tough and plus all the weapons he got, is what is required to beat Djoker. Federer has the game, but a lot of the elements he seems no longer possesses, and he chokes quite a bit when leading in sets or matches. Nadal on the other hand doesn't have nearly the same penetrating game, thus he needed to engage in long rallies and that plays into Djoker's best strength.
