Goalkeeper Lammens has shown great promise in his youth, with 56 senior appearances in the Belgian Jupiler Pro League and one Champions League appearance under his belt. His impressive statistics, including a 76.8% save percentage and 81.8% sweeper keeping rate, have caught the attention of Manchester United's management.

Meanwhile, Emi Martinez has been a reliable goalkeeper for Aston Villa, with a 100% record in sweeper keepings and a save percentage of around 60-80% over the past few seasons. However, his age and experience may have been a deciding factor in Manchester United's decision to opt for the younger Lammens.

Belgian media have praised Lammens' shot-stopping ability, reflexes, and proactive approach to the game. Even Real Madrid's Thibaut Courtois has spoken highly of Lammens, calling him a "huge talent" with a style well-suited to the Premier League.

However, Lammens' lack of experience is a concern, and he will need to improve his distribution and decision-making to become a top-class goalkeeper. His pass completion rate, while improving, is still not fantastic, and he will need to work on launching the ball upfield more effectively.

Manchester United's management will be watching Lammens closely to see if he can settle quickly and produce his best work. If he succeeds, the £18.1m signing could prove to be a bargain. But if not, the Red Devils will have to go back to the drawing board.

The pressure is on Lammens to deliver, and he will need to work hard to establish himself as Manchester United's number one goalkeeper. Only time will tell if he has what it takes to succeed at the highest level.
