It will be a "major surprise" if Novak Djokovic does not win 25 Grand Slams, says tennis legend John McEnroe.
Djokovic, 34, claimed a record-equalling 20th men's title by beating Italy's Matteo Berrettini in Sunday's Wimbledon final, matching the record held by Roger Federer and Rafael Nadal.
Only Margaret Court, Serena Williams and Steffi Graf have more, but McEnroe expects Djokovic to surpass them too.
"Djokovic is playing better than he has ever played," he told BBC Sport.
"I think he will probably win at least four or five more, obviously depending on staying healthy.
