Despite the uncertainty at Old Trafford, the Red Devils are said to be close to sealing a £30m deal for the teenager, who will earn a staggering £100,000-per-week.
Departed manager David Moyes is believed to have been a major factor in the prospective move, with the Scot having convinced the teenager – who may become the highest paid player below the age of 20 in England – to opt against a switch to Chelsea – the team he supports.
It is understood that the wages offered by the Premier League champions are far above that that the Blues were willing to pay.
Shaw is set to become Patrice Evra’s successor, with the French ace looking likely to leave on a free transfer this summer.
If the transfer goes through it is set to spark a massive summer at United, in which the club are expected to spend well over £150m to rebuild their first-team squad after a disastrous campaign.
Shaw has also been linked with Liverpool and Tottenham, and is thought of as one of England’s finest young talents.
After establishing himself as a regular starter at Southampton, he could also be a part of the Three Lions’ World Cup squad after recently making his international debut.
