Tennis legend Boris Becker has pledged to help current number one Novak Djokovic win more championships after the "perfect year" in 2014.
Becker, who made history by becoming the youngest ever winner of the prestigious Wimbledon tournament at 17, started coaching Djokovic at the end of last year. Under Becker, Djokovic won seven titles, including Wimbledon in the summer of 2014, propelling him back to the number one ranking.
Becker told CNBC this last year had been an ace for the duo.
"Well we have finished the year as number one, so you know it was pretty much a perfect year. He (Djokovic ) won the Wimbledon tournament earlier in the year and became world champion," Becker said in an interview on CNBC.
"I couldn't ask for a better year. The opposition doesn't sleep…we have to go back to the practice courts soon."
