This was reported by journalist Samuel Luckhurst of the Manchester Evening News, according to NTB. The Daily Mail says this is a precautionary measure.
The BBC, citing sources, says that Ferguson was not acutely ill when he left the stadium but was taken to hospital for medical reasons as a precaution.
The Scot, who led Manchester United to multiple titles during his 27 years as manager, suffered a brain hemorrhage in 2018 and became seriously ill.
The BBC writes that official representatives of Manchester United are optimistic that Ferguson will soon be able to return home after his hospital visit.
