Baleba would have been an ideal signing for United, offering both defensive and attacking abilities. His engine would have allowed players like Bruno Fernandes to focus on creating chances in the final third. However, the deal is off, and United must now consider alternative options to address their central midfield needs.

One position that remains a concern is the pivot role, which will likely be played by Bruno Fernandes this season. Casemiro, while still a useful asset, is 33 years old and questions remain about his ability to keep up with the demands of the position. Manuel Ugarte is good when opposition players are running at him, but struggles on the counter, while Kobbie Mainoo is too attacking to be played in a pivot with Fernandes.

With these concerns in mind, here are five alternative midfielders that United could consider signing:

Amadou Onana (Aston Villa)

Onana, 24, is a Premier League-proven player who has the experience and leadership skills that United are looking for. He's signed from Everton for a reported fee of £50 million and has shown his proficiency as a ball-winning midfielder, with 26 recoveries, 131 duels won, and 30 tackles won last season. However, fitness is a concern, as he missed 17 games across all competitions for Unai Emery last season.

Lamine Camara (Monaco)

For a relatively low fee, United could take a chance on Camara, a 21-year-old midfielder who is fantastic at connecting the defence and midfield. He's received the ball under pressure and progressed it up field without breaking the bank. While he may not be the perfect solution, he could be an excellent stopgap if Baleba becomes available down the line.

Morten Hjulmand (Sporting CP)

Hjulmand, 26, played a key role under Amorim during his time at Sporting. He's a good fit for United's system, and his statistics are impressive, with 46 tackles won, 199 duels won, and 46 interceptions. While he may not have the same profile as Baleba, he's a solid option for United.

Pablo Barrios (Atletico Madrid)

Barrios, 22, is a talented midfielder who has established himself as one of La Liga's best under Diego Simeone. He's the archetype of the type of midfielder that United are looking for, offering tenacity, work rate, and a little nasty streak. However, any move for him would come at a high cost and may completely end United's interest in Baleba.

Quinten Timber (Feyenoord)

Timber, 24, is a risk worth taking for United. He's a talented midfielder who has impressed in the Eredivisie, with 24 tackles won, 98 duels won, and 57 recoveries last season. However, historically, players brought in from the Netherlands have struggled in the Premier League, excluding Luis Suarez.
