Jo-Wilfried Tsonga has admitted that Andy Murray will have an advantage over him when the two clash in Friday's Wimbledon semi-final.
The number five seed said that the Scot's prior experience of playing under the Centre Court roof will work in his opponent's favour.
"He will know the condition. Of course it is an advantage. I will just play and we'll see," he said.
"Last year it was already something huge to reach the semis."
Tsonga booked his place in the last four with a 7-6 4-6 7-6 6-2 win over Philipp Kohlschreiber.
Murray overcame David Ferrer 6-7 7-6 6-4 7-6.
