Manchester United received a heavy blow with the injury of their first-choice goalkeeper Andre Onana shortly after returning to training at Carrington, which threatens to keep him out for 6 to 8 weeks, according to the British newspaper "Telegraph".

Onana's absence puts the coaching staff led by Ruben Amorim in a difficult position, especially with the limited experience of the backup goalkeeper, Turkish Altay Bayındır, and the club's reliance on Tom Heaton as a backup option despite not being the ideal goalkeeper for the team.

Amid this crisis, Manchester United has begun to consider signing a new goalkeeper during the summer transfer window, while continuously monitoring Onana's physical condition and the chances of him returning in time for the pre-season.

Although the name Emiliano Martinez has been linked with a move to the Red Devils, Aston Villa's financial demands complicate the deal, while the performance level of young goalkeeper Radek Vitek, returning from a loan in Austria, raises some doubts about his readiness to take on the responsibility.

These concerns come amid Onana's fluctuating performance last season, where he made several impactful mistakes that affected the team's results in the Europa League and the English Premier League, increasing the pressure on the goalkeeping situation at Manchester United.
