Manchester United legend, Paul McGrath has exposed the greatest weakness of the club's new signing, Harry Maguire.
McGrath explained that Maguire has a big weakness in carrying the ball out from defence.
We reported on Monday that Man United signed Harry Maguire from Leicester City.
The England international signed a six-year contract with the option of a further year at Old Trafford.
"I would trust that United will put in a system at the back to cover Maguire's big weakness - one that will be exploited by the likes of Manchester City and Liverpool, and also Europe's elite strikers whenever Manchester United return to the Champions League," McGrath told the Irish Independent.
"Harry likes to carry the ball out - something all the top clubs look to encourage. But when the tactic goes wrong, as it occasionally must, he doesn't have the blinding pace of Virgil van Dijk or Real Madrid 's Raphael Varane to get back and tidy up.
"So there will have to be a bit of coaching work done at Carrington over the next few weeks, so that United's other defenders in any game realise that they must not get caught going up the pitch alongside Maguire - someone must always be 'minding the house'."
