Federer Present During Shanghai Final: "I Was Watching to See How He Reacted," Says Vacherot

Roger Federer attended the Masters 1000 final between Arthur Rinderknech and Valentin Vacherot. Additional pressure or a source of motivation?
The Monegasque answered in a press conference: "Yes, I'm not going to lie, after winning or losing a few points, I would glance at him out of the corner of my eye to see how he reacted to certain shots.
It was incredible to have him there. Every time he appeared on the screen, I think it made more noise than after some of the big points we played. That shows how incredible and amazing he is for this sport, even though he stopped playing tennis four or five years ago, I believe.
Yes, I was able to play against Novak yesterday. I was able to meet Roger today. Even outside of tennis, it's been a crazy week for me."
