Of course, I couldn't move 100%. I couldn't really push off on my serve either, which is obviously very, very important for me against him.

I'll look into it with him and see what it is and if we can do anything about it. Maybe we can make an injection, and then I'll come to Turin at some point," he added.Ahead of the Paris Masters, Zverev competed at the Vienna Open, where he reached the final.
