Sir Alex Ferguson has been taken to hospital after feeling unwell at Old Trafford before the Manchester United vs Liverpool game.
Sky Sports News understands he is conscious and has had precautionary checks.
Sir Alex, 84, is a regular at Manchester United games both home and away, having managed the team for nearly 27 years until his retirement in 2013.
He joined the Red Devils in 1986 and was in charge for 1,500 games, leading United to 13 Premier League titles and two Champions League triumphs.
He then served as an ambassador for the club until 2025.
In his illustrious career, he claimed 38 trophies with United, as well as three Scottish league titles and four Scottish Cups with Aberdeen.
Sir Alex also managed St Mirren and Scotland, including at the 1986 World Cup, following a playing career as a forward which saw him finish top scorer in the Scottish Division One in 1965/66.
In May 2018, he had emergency surgery for a brain haemorrhage after falling ill at home.
He recovered from the surgery and was given a standing ovation as he returned to Old Trafford in September that year.
