A fist pump, a point to his box of supporters, and a roar of delight.

Andy Murray returns to the Australian Open final for the fourth time after a four set victory.

The world number 6 beat Thomas Berdych  6-7(6-8) 6-0 6-3 7-5 at the Rod Laver arena to set up his eighth grand slam final.

He will play the winner of tomorrow’s  semi-final between Novak Djokovic and Stan Wawrinka.

Murray started poorly, struggling against the serve of his Czech opponent,   and offering far too many chances for Berdych on his own second serve.

Berdych broke first, then Murray staged a mini revival late in the first set, before losing a tense tie-breaker.

Murray was clearly annoyed with his game.

After the match he was asked what he had said to himself between sets:

Probably nothing I can repeat on TV

He was determined to put things right in the second set, and how.

After a first set that took 77 minutes, the Scot blew his opponent away in under half an hour to level the match.

With his forehand now working well, his movement improving and the crowd on his side, he took the third set 6-3.

Berdych was not out of this yet, recovering his composure, and his serve to take the fourth set to 5-5.

His resistance was finally broken after some outstanding defence by his opponent, as well as an untimely double fault which gave Murray the chance to serve for the match.

Despite beating home favourite Nick Kyrgios in the quarter final, the Australian crowd seem to have taken Andy Murray to heart, responding warmly to him in his post match interview.

It also hasn’t gone unnoticed that the Scot seems to be almost enjoying himself.

He found time to make a wry joke about his new coach, Amélie Mauresmo, and the impact she has had on his game:

It shows that women can be good coaches after all

After three losing appearances in this tournament, and taking into account the Australian love of an underdog, Murray can expect a fantastic response from the Rod Laver arena on Sunday – whoever he faces.
