Jeremy Chardy has admitted that he had to battle through injury and tiredness as he reached his first grand slam quarter-final.
"I always play bad in Australia," Chardy said after the match. "But this time, I played well.
"I am feeling good on the court. It was a difficult match in the beginning and I was tired but it was the fourth round in a grand slam so I had to stay strong in my head.
"I have pain [in my knee] but I am in the quarters, I have to forget about that."
