Six-time grand slam winner and former world number one Boris Becker has been appointed as Novak Djokovic's new head coach.

Becker replaces Marian Vajda as coach to the world number two with Djokovic looking to usurp Rafael Nadal at the rankings summit and add to his six grand slam titles.

Vajda, who has held the reigns since 2006, will continue to be part of the Serb's team as he looks ahead to his future with Becker at the helm.

"Boris brings a fresh approach and together with Vajda he will make a winning combination," said Djokovic.

"Boris is a true legend, someone who has great tennis knowledge, and his experience will help me win new trophies, Grand Slams and other tournaments.

"He is a great person too, and I am sure he will fit in our team in the best possible way. The team is now strengthened and we hope for maximum results.

"My goal for 2014 is to play my best tennis and to get in shape for the grand slams and Masters 1000. These tournaments have the most weight in our sport, and I want to prove my worth at them."

Becker, who has not coached regularly before, shot to fame when he won Wimbledon unseeded at the age of 17.

The German then went on to claim 64 ATP Tour titles during his 15-year career.

"I am proud Novak invited me to become his head coach," said Becker.

"I am sure we can achieve great things together."

As the Vajda-Djokovic comes to an end, the coach, who will attend events in Indian Wells, Madrid, Toronto and Beijing next year, has welcomed Becker's arrival.

"I realised that Novak needed a new head coach in order for him to continue improving certain parts of the game," he said.
