A danger this Squire?

23 year old German who comes out of nowhere after a good tournament at Roland, who are you Henri Squire?

My first reaction after seeing his match live against Purcell at Roland was: damn, he's going to be boring playing on grass! Tall 1m96, excellent server, aggressive player who comes to take the net when he can, he really has what it takes to perform on grass. He has little experience on this surface at the moment but at his age that's normal, I especially see an interesting profile who arrives with great confidence. He has an excellent ratio indoors and he can clearly explode during this season on grass. He will be opposed to Hanfmann, another local but less efficient player on grass, which is his worst surface. His serving kick is almost useless, and his large size doesn't help. Experience remains on his side but the current dynamic and the possible level of Squire on grass in the future make me want to try something..
