Former United defender Paul Parker has been warned the club against potential summer transfers for Leicester playmaker James Maddison and Aston Villa midfielder Jack Grealish.
“Manchester United need to sign proven players but the one who has proven himself [Maddison] is not going to leave Leicester,” he told Metro.
“He’s not going to move unless Leicester get offered ridiculous money, like they were for Maguire.
“Leicester couldn’t believe their luck with that one. So you go with Maddison [over Grealish] but can they get a deal?
“Grealish for me is still potential, there’s been a lot of talk, and he hasn’t really done it on a consistent basis.”
The club have been linked with both players ahead of summer, and are likely to sign them in a bid to add attacking forte to the team.
