What winners do when they lose?

They get up and plan for what's next.

As soon as Novak Djokovic was defeated in the US Open 2013 final and knocked out of the first place by Rafa Nadal he contacted Boris Becker who accepted to coach him.

Novak Djokovic approached me day he lost top spot - Becker

Novak Djokovic approached Boris Becker to become his coach on the day the Serb lost his world number one ranking, the German has revealed.

Rafael Nadal usurped Djokovic, 26, by reaching the China Open final in October, a few weeks after defeating the Serb in the US Open final.

"I was approached by Novak and his manager while he was playing in Beijing," Becker told BBC Sport.

"I was surprised - I didn't expect the phone call. I was very honoured."

Djokovic, who has won six major titles, will start work with Becker before the Australian Open, which starts on 13 January.

The Serb's long-time coach Marian Vajda will continue as part of his team.

Speaking to BBC Sport tennis correspondent Russell Fuller, Becker revealed he had a number of discussions with Djokovic after the initial contact before deciding he wanted to coach full-time.

"This isn't a half-hearted job, it wouldn't be right for him or for me," explained Becker.

"You're in it to win it. You either go at it fully or you don't - either I commit myself or I don't commit myself.

"I said 'I want to meet you and see how much you want it, how much that fire is burning inside you, how much is left, and what I can bring to the table'."

The champ wasted no time. As the old song says - "pick yourself up, dust yourself off and start all over again..."
