Boris Becker believes Maria Sharapova has paid her dues and deserves a second chance when she returns to tennis in April at the end of her 15-month doping ban.

Sharapova, a five-time Grand Slam champion, failed a dope test for the drug meldonium at the 2016 Australian Open and was suspended for two years by the International Tennis Federation (ITF).

The Russian's ban was then cut by nine months by the Court of Arbitration for Sport (CAS) last October, meaning she is free to return from April 26.
