Andy Murray has said that he is expecting a "tough" match against Tomas Berdych in the Wimbledon semi-finals on Friday.
The world number two is the highest remaining seed in the competition, but needed five sets to overcome Jo-Wilfried Tsonga in his quarter-final on Wednesday.
However, Murray's recent record against Berdych is a good one, and he hopes that his newfound aggressiveness under returning coach Ivan Lendl will help him to extend his four-match winning streak against the Czech.
"I know it will be a tough match. I played well against him the last couple of years. 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," Murray told reporters.
"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. We've never played on grass before. We've played a few times over the last couple of years on different surfaces, but never on grass.
"I'll have to have a look and see some of his matches to get an idea of maybe some of the things he does differently on the grass courts, what his strengths are, maybe some of the things he struggles with a bit. Obviously he's a big guy who serves well. When he's dictating the points, he hits a big, big ball. He's a powerful guy. Ideally, I don't want to have him dictating all of the points because then I'll be doing a lot of running."
Murray is bidding to win Wimbledon for the second time having previously triumphed three years ago.
