Onana returned from injury recently and was at fault for two goals in a loss to Grimsby Town, a League Two club. Meanwhile, Bayindir made an error in a recent win against Burnley, which led Amorim to pursue Lammens as the solution to their goalkeeping woes.

Lammens has played for Royal Antwerp since the summer of 2023, after joining from Club Brugge. In the 2025/26 season, he made four appearances, conceding a goal in each match. Despite his young age, Lammens is an experienced goalkeeper, but he has no Premier League experience, which makes this move a significant challenge for him.

As a contingency plan, United has also made inquiries about Emiliano Martínez, a goalkeeper from Aston Villa, whose future with the club is uncertain. However, Lammens is Amorim's top priority, and the deal is reportedly agreed upon.
