Roger Federer: John McEnroe says it would be 'unbelievable' if 20-time Grand Slam champion could win again
John McEnroe thinks it would be “unbelievable” if Roger Federer could return to his highest level again – but does not want to see him on tour playing at “80 per cent”. Federer, 40, returned from a lengthy lay-off in March last year but only played 13 matches before shutting down his season. Ad/> He has since undergone another knee surgery and has suggested he will not be ready to return in time for Wimbledon this year.
