Novak Djokovic jokingly confessed to feeling guilty after practising on the serene Centre Court grass.
Djokovic faced Carlos Alcaraz in a glitzy practice set on Wimbledon’s main stage.
“Of course, yesterday obviously I was practising with Carlos, and obviously the tradition changed in the last few years that you get to hit a few balls on Centre Court.
“I thought that tradition will never change, but I guess everything is moving forward. Obviously it’s a huge privilege to be on virgin fresh grass before the tournament starts.
“It did feel a bit strange to be honest, and I almost felt a bit bad for ruining the grass and sliding on it.”
