German tennis legend Boris Becker backed controversial Romanian former tennis great Ilie Nastase in a series of tweets on Friday, a month after Nastase was in the middle of a nasty scandal where he directed racist remarks towards Serena Wiliams’ unborn baby.

The six-time Grand Slam winner went on to defend Nastase but called on him to apologise to Serena Williams and be fined by the International Tennis Federation and the Women’s Tennis Association with the money going to the charities. He then added that the Romanian legend should not be banned by the tennis community.

At the Federation Cup tie between Great Britain and Romania in April, Nastase caused a furore when he made offensive remarks about Williams’ unborn child, while also making sexist remarks towards British captain Anne Keothavong.

He was finally expelled from the tie due to “serious misconduct” after a rant at the umpire.
