Andy Murray has dismissed the impact his former coach can have when the top Scot takes on Tomas Berdych in their Australian Open semi-final.

Big-serving Berdych has Murray’s former coach Dani Vallverdu in his corner and has been glowing in his contribution in his march into the final four.

Murray worked with Vallverdu for five years until their split two months ago.

Despite the coach’s intimate knowledge of the sixth seed’s game, Murray said it would count for little once he and the seventh-seeded Czech crossed the white lines at Rod Laver on tonight.

“My goal isn’t to beat Dani; my goal is to beat Berdych,” Murray said.

“I’m not playing against him.

“I don’t think loads of sports people talk about other player’s coaches and managers.

“Coaches talk about each other, but it’s not for me to discuss.”

Murray, who now has former women’s world No.1 Amelie Mauresmo in his coach’s box, said he still benefits from his relationship with Vallverdu.

“We’ll see how the match plays out and what the tactics are and stuff,” he said.

“But I also know what Dani thinks of Berdych’s game because he’s told me, so it works both ways.”

Berdych booked his final four berth by putting Rafael Nadal out of the tournament shortly before Murray beat exciting Australian teenager Nick Kyrgios.

Stan Wawrinka and world No.1 Novak Djokovic will meet in the other semi-final after both had straight-set wins.

Defending champion Wawrinka overcame Japan’s Kei Nishikori while Djokovic dominated Canadian Milos Raonic.

The final two contenders for the women’s title will be decided on Rod Laver Arena during the day session.

Rising teenage star Madison Keys will clash with veteran American, world No.1 Serena Williams while the other semi-final is an all-Russian affair with Maria Sharapova and 10th seed Ekaterina Makarova.

Williams is playing for her first finals berth in Melbourne since 2010.

Sharapova can regain the top ranking should she win and Williams lose.
