“What I’ve been really trying to work on is mental strength and preparation for every single match,” admits Berdych. “They are very important aspects of today’s game. Especially now. Everybody can play a good forehand and backhand. There is no difference at all. It’s really just about the small details and one of them is the mental preparation, which I’ve been trying to improve. I believe I did so, but you can improve these aspects a lot. I hope this is something that can take me higher."
