John McEnroe has said that 'no player in history' has had to deal with the amount of pressure that Andy Murray has had to cope with.

The Scot will play in his fourth Grand Slam final against Roger Federer this afternoon, hoping to become to first British man to win a major since Fred Perry in 1936.

McEnroe said that the weight of expectation must weigh heavy on Murray's shoulders and gave credit to the 25-year-old for not buckling.

"When he won in the semi-final, there wasn't a whole lot of ­excitement," said McEnroe. "There was certainly a large sense of relief. I saw tears.

"The stress that he has been under – in any sport I can think of, certainly an individual sport – has been ­incredible. I was never under that type of pressure and expectation, so I have got to hand it to Murray.

"I don't think there's any player in history who has been under more pressure than him to try to break this streak. That kind of pressure is hard to deal with. I had to deal with a lot in my career but I never felt like I was under anywhere near the pressure Andy had been under during his ­career."

McEnroe won three Wimbledon titles during his career.
