Zverev " if Roger Plays his best tennis..."

This is What Misha Zverev said before his match against Roger Federer : 

"If Roger plays his best Tennis, you can only collect the balls, and hope that it will soon be over"

“I don't know if it's something I can do or he can do to himself. I'll maybe give him a mean, angry look before the match. I have no idea,” Zverev said. “We'll see what's going to happen. So far every time we have seen each other, we've been joking around in the locker room or warm-up area. He seemed pretty relaxed to me.”
