Top seed Novak Djokovic has said that he hopes coach Boris Becker can help him end his Grand Slam drought at Wimbledon.
Djokovic has failed to win a major title since the Australian Open in 2013, losing in three Slam finals.
"It's one of the reasons why Boris is on board," said Djokovic, who won Wimbledon in 2011.
Despite teaming up with Becker, Djokovic lost the Australian Open quarter-finals and the French Open final this year.
Becker, 46, was the youngest ever winner of Wimbledon at the age of 17 years 227 days in 1985.
