"His biggest achievement is dominance that he had early on" - Wilander on Federer's career

"I think his biggest achievement so far is the dominance that he had early on as soon as he won his first major. The dominance he had towards Lleyton Hewitt, Marat Safin, Andy Roddick, Juan Carlos Ferrero, who were all great players. And then Federer just literally went out and won everything except the French Open."

"Second thing is to actually step up and win the French Open when [Rafa] Nadal lost to [Robin] Soderling. To actually take that pressure and say okay, this is my chance and then actually delivering. Then I think the big thing for me, the biggest accomplishment is him coming back and winning three majors from 2017. He hadn't won four, five or six years and then suddenly wins the Australian, Wimbledon and then the Australian again in 2018."

"I think tennis wise, that is probably his biggest accomplishment because he is fighting against a generation that is five or six years younger than him. And there's nearly no players in the history of the game that have been able to keep up with the generation that's knocking on the door because the game moves in one direction."

"I don't think Federer is going to come back unless he feels that he has a level where he can compete with most guys on tour. Does he have it inside of him in his confidence to go out on the centre court at Wimbledon and play Novak Djokovic next year in the quarters and feel like he has a chance? That's again, something that I don't think he knows."
