Manchester United manager Michael Carrick has spoken openly about the need for balance after a summer in which the club spent more than £150m strengthening a midfield identified as the priority area for recruitment.

The spending spree brought in three new faces: Andrey Santos from Chelsea for £48m, Youri Tielemans from Aston Villa for £35m, and Cameroon international Carlos Baleba for £70m — the last of those among the top-10 most expensive signings in United's history.

A crowded engine room

Add Kobbie Mainoo and Bruno Fernandes to that list and Carrick has five senior central midfielders competing for a limited number of places. The arrival of Santos and Tielemans followed United missing out on their primary targets, Elliott Anderson and Mateus Fernandes, but the club moved swiftly once those deals fell through.

Each player brings a distinct set of qualities. Baleba offers pace, defensive aggression, and sharp positional awareness. Tielemans contributes composure in possession, precise passing, and creative vision. Santos excels in one-on-one duels, screens the back four from a deep position, and uses short bursts to break defensive lines. Mainoo, meanwhile, has an instinctive ability to receive the ball in tight areas and drive United forward.

Former Manchester United goalkeeper Ben Foster sparked debate on social media by suggesting Mainoo is not yet a guaranteed starter, and would benefit from a loan spell where he would be relied upon every week. The reaction online was largely critical of that view, with many supporters insisting Mainoo should be among the first names on any team sheet.

Champions League rotation a necessity

Carrick is navigating the demands of a return to UEFA Champions League football for the first time in several seasons. Last year, United had just two midweek fixtures in the second half of the campaign, enjoying recovery gaps of 13 and 11 days after those matches. That luxury has gone.

United face five matches in 16 days to open the season, beginning with the trip to Everton. Should they progress in the EFL Cup, the squad will have no free midweek until Christmas — a gruelling schedule that makes rotation across the midfield not merely possible but essential.

Brazil midfielder Casemiro departed at the end of his contract, while Uruguay's Manuel Ugarte — who was already likely to leave the club — is sidelined until next year after suffering an anterior cruciate ligament injury at the World Cup. Mason Mount also suffered an ill-timed setback in early August, a reminder of his troubling injury record.
