Sir Alex Ferguson revealed the thing he hated most about being Manchester United manager during a recent interview with American broadcaster PBS.
The Old Trafford legend retired at the end of last season after 26 years in charge of the Red Devils, having become the most decorated manager in British football history and leading his team to 13 of a record 20 league titles.
The last of these was last season, which saw Manchester United edge one ahead of Liverpool as the most successful club in the English league.
Despite winning numerous trophies and awards, Ferguson admitted it was not always enjoyable being in charge of one of the most famous clubs in world football.
Having been in charge the best part of three decades it was only natural that Ferguson would have to make some difficult decisions regarding his squad and refreshing the playing staff at Old Trafford, though claimed telling his stars they were past it was the most difficult aspect of his time in charge of Manchester United.
"Well the horrible part of the job really is when you have players who have been with you for years the evidence is always on the football field," he said.
"So when you see a player and you notice that the level has started to dip, there is no point on waiting another two years. You have to act because you will only hurt yourself.
"He’ll not want to recognise that the day has come when he has had his time. To have to say that to a player and make the change is very, very difficult. You can only do that if you have a system where you can fill the gaps and rebuild the team."
Ferguson may have felt bad about doing this, but it was this talent for not letting sentiment creep into his selection thinking and a ruthless streak that many believe was one of the things that made him such a brilliant manager.
