Sir Alex Ferguson has admitted he is finally feeling the strain of 15 years in the Manchester United hotseat.
The 59-year-old has enjoyed an unparalleled run of success during his time at Old Trafford, but this season has seen United hitting the headlines over a string of defeats and the controversial departure of Jaap Stam.
Ferguson told Italian sports magazine Guerin Sportivo: "I have been a manager for 28 years and the game has changed. It is infinitely more difficult these days.
"There is too much expectation, too much pressure. It has become very difficult for me to take.
Ferguson has also revealed the chance to spend more time with his family was one of the main reasons for his decision to quit United at the end of the season.
"I didn't see them grow up, but I did see a lot of young footballers grow up. That is why I think they see me more as a friend than a father.
"That is, perhaps, one of the big reasons why I am leaving. I hope I can make up for lost time".
