Manchester United are preparing for a major defensive overhaul next summer, with the club reportedly ready to sign up to three defenders as Michael Carrick continues to reshape his squad at Old Trafford.
United concentrated on midfield during the 2026 transfer window, but the back line is expected to become the next major focus in 2027. The club’s plans, reported by The Sun, could see several established defenders face decisive seasons over their futures.
Luke Shaw, Harry Maguire, Lisandro Martinez and Matthijs de Ligt are all understood to be under scrutiny during the current campaign. Their performances and, crucially, their availability will help determine whether they remain part of Carrick’s longer-term plans.
Manchester United’s defensive overhaul could begin next summer
Shaw, 31, is entering the final year of his contract and may have to accept reduced terms if he is to extend his stay. The left-back’s fitness record has been a recurring concern, despite his ability to operate at a high level when available.
Maguire’s position is also uncertain, even though the former England captain continues to offer experience and leadership. Martinez and De Ligt face similar questions after suffering significant injury problems, with United needing greater continuity in defence if they are to build a settled side.

United’s right-backs could also be assessed over the course of the season. Diogo Dalot and Noussair Mazraoui may have to establish themselves as reliable long-term options, while the club’s interest in Newcastle United left-back Lewis Hall could be revived after an approach was rejected in the latest transfer window.
Newcastle reportedly told United that Hall was not for sale this summer, leaving Carrick without the additional senior left-back he wanted. The 21-year-old remains a long-term target, according to Sky Sports.

The timing of the proposed rebuild reflects the wider recruitment strategy at Old Trafford. United have already invested heavily in other areas of the squad, while Carrick’s continuation as head coach was confirmed in May with a contract running until 2028.

Any defensive changes will depend on how the current players perform during the 2026-27 season. Yoro and Heaven are not expected to be swept aside, but the futures of the senior defenders could be determined by their fitness, consistency and ability to provide Carrick with a dependable foundation.
