I am also curious why De Chaunac had some claims about a guy sitting in the front row. I suppose he was fired from the stands at the final stages of the 3rd set.
It seemed to me he was really getting frustated about every little thing, crowd, linesmen etc. He obviously was way out of his depth and getting destroyed so needed to vent his anger. I felt sorry for the poor guy in the stands, he kept apologising until he was blue in the face but De Chauanac kept going on and on.
