Boris Becker has urged tennis stars Novak Djokovic and Rafael Nadal to prolong their careers amid retirement rumours.
Spanish tennis icon Nadal aims to overcome injury ahead of the French Open in May when he hopes to win the clay court tournament for a 14th time. However, retirement rumours have been raised after the 36-year-old struggled with a leg injury while exiting the Australian Open in January
Nadal has withdrawn from both the Indian Wells and Miami Masters this month delaying his return to competitive action until April. His absence means the world No.8 risks dropping out of the top-10 rankings for the first time in 18 years.
