What's up with Lundgren and Wawrinka's box getting up on their feet and screaming every time Wawrinka wins a good point, or an important game?
I don't remember Lundgren doing this when he coached Federer or Safin
Obviously he's just trying to keep Wawrinka pumped up during a match, but is this really necessary? He even has the typically quiet Wawrinka yelling a lot now too
It has to be quite annoying for Wawrinka's opponents
