Andy Murray has said that he is expecting a tough match against Jo-Wilfried Tsonga in the semi-finals of the Aegon Championships at Queen's tomorrow.
The world number two sealed his place in the last four of the tournament with a straight-sets win over Benjamin Becker earlier today.
The Scot told BBC Sport: "It will be a big step up and also a really big test for me, because he's been playing some great tennis the last couple of months.
"He obviously had a very good run at the French Open, and he's a top grass-court player. He's one of the best in the world on this surface.
"I have had some tough matches with him on the grass before, so tomorrow will be the same."
The match will be a repeat of the 2011 final at Queen's, which saw Murray win the tournament for the second time in his career.
