Jeremy Chardy has admitted that he had to battle through injury and tiredness as he reached his first grand slam quarter-final.
Chardy beat Andreas Seppi this morning, coming from behind to win in four sets.
The Frenchman now awaits the winner of the match between Gilles Simon and Andy Murray.
"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."
Chardy had knocked out Juan Martin del Potro in round three.
