Sources: Man United have four defenders on shortlist as Maguire future remains uncertain

Manchester United are in the midst of a significant squad rebuild under new head coach Ruben Amorim, with defensive restructuring emerging as one of the club’s top priorities.

The Portuguese manager has wasted little time in stamping his identity on the team, with more signings set to be made next year, sources close to the agents industry have informed CaughtOffside.

One of the most notable shifts under Amorim has been the abandonment of the traditional back four in favour of a 3-4-3 system.
