Former Manchester United manager Sir Alex Ferguson has admitted the squad needed “a big injection” of players.
Ferguson retired in 2013 but successor David Moyes was sacked in April as United struggled to seventh position last term, their lowest Premier League finish.
Six new players were brought in at a cost of £150m, including Angel Di Maria for a British record fee of £59.7m
“It was really important because you need quality at Manchester United, you need the best players,” Ferguson said.
The 72-year-old Scotsman, who won 38 trophies in his 26 years at United, told MUTV: “That’s the way the game is going today with fees likes £85m for Gareth Bale. When you can identify ability like that needed by Manchester United, they have the resources to do that.
“Those are fees I never quite equalled but nonetheless they were needing quite a big injection this year.”
