Andy Murray, who overcame Jo-Wilfried Tsonga in five sets to reach the semifinal of Wimbledon, says that having Ivan Lendl back in his box has inspired him.

“I think it's beneficial having him there, for sure, because I trust him,” Murray said. “[I] have a lot of confidence in him. So he can help when I'm on the court a little bit, just his presence. Might be a small amount, but like I said, every little bit helps."

Lendl won eight Grand Slam singles titles in his illustrious career. In 2012 and 2013, with Lendl by his side, Murray won his only two Grand Slams. Lendl ended their partnership the following year, but returned to help Murray at the beginning of the grass-court season.

Murray said that Lendl's presence is especially significant between matches and tournaments.

“The pre-match stuff, the work that you do in preparation for the matches, is where you get the big benefit,” the Scot said. “When this tournament's finished, the training weeks are really where I think you get the biggest benefit.”

Murray will face Tomas Berdych in the semis. The Czech once led their head to head 6-4, but Murray has won their last four contests. Murray bested Berdych in the Australian Open semis last year, and then beat him again in Miami and Shanghai. They’ve played once this year, in Madrid, and Murray won, 6-3, 6-2.

“I played well against him the last couple of years,” Murray said. “It's nice that the players I'm playing against say I'm playing more aggressive, because everyone's only said I've played aggressive when Ivan has been coaching me. The last few years I have been playing more aggressive tennis, playing with a little bit more variety, for sure. That's worked well against him.

"In the past, I hadn't [had] such good results against him. The last couple years it's been good.”
