Fatigued Frenchman Gilles Simon candidly admits he has little chance of upsetting Andy Murray in the Australian Open fourth round and might not even make it through Monday's match.
Even at his best, winning would be a long shot.
Simon has lost their past nine meetings, winning just two sets in that time.
He will be in far from top shape after barely making it through his four hour, 43 minute third-round battle with fellow Frenchman Gael Monfils.
Their five-setter finished in the early hours of Sunday and Simon didn't make it to bed until about 5am (AEDT) after hours of post-match treatment for numerous ailments.
They included elbow pain which severely restricted his serving and hitting speed.
Treatment aided his recovery only a limited amount.
"There is no miracle, so a massage, stretching, because all parts of the body were painful," he said.
His clash with Murray is not scheduled to start until at least 5pm Monday but Simon said that might not be long enough.
"I have no choice. I will just do my best to be ready for the match," the 14th seed said.
"The thing is, it's difficult to win 6-2 6-3 6-2 against Andy. I'm not sure if we play longer than that that I will be able to make it to the end."
Reminded of his previous poor record against Murray, he noted: "And I was in better shape when I was going on the court."
"I don't have to explain to you how strong he is. Of course it will be really, really difficult.
"At the moment I'm just happy that I won the last one.
"I will just try to go and take my chance even if I don't have a lot of chance to win this one."
