Royal Antwerp's former goalkeeper, Senne Lammens, has completed a significant transfer to Manchester United, a move valued at up to £21.7 million. This high-profile signing sees the 23-year-old depart the Belgian club for Old Trafford, marking a new chapter in his career.

However, this transfer has raised "alarm bells" among Premier League rivals. Several top-flight clubs had previously scouted Lammens but ultimately decided against pursuing him due to significant doubts about his suitability for the demanding nature of English football.

Manchester United proceeded with the acquisition of Lammens, notably rejecting the opportunity to sign the more experienced Emi Martinez from Aston Villa. This decision to overlook Martinez's proven Premier League pedigree in favour of Lammens has been a point of discussion.

Reports from Lammens' native Belgium indicated that clubs like Sunderland and Leeds United had initially enquired about the goalkeeper. However, they quickly withdrew their interest upon learning of Royal Antwerp's hefty asking price, further highlighting the perceived risk.

Scouts acknowledged Senne Lammens' potential but concluded that the athletic, mental, physical, and technical tests posed by the Premier League far exceed those of most other leagues. They felt it would be a considerable risk to immediately place him in a first-choice role in England.

It remains to be seen how Senne Lammens will integrate into the Manchester United squad and whether he will secure a spot in the first XI immediately. The move from Royal Antwerp to the Premier League represents a significant step up, with all eyes on his adaptation.
