Brentford have put their winter move for Antonio Nusa on hold until the summer transfer window.
The Bees were very eager to bring in the 18-year-old for a club record fee from Club Brugge.
However, The Standard says the 31.5 million transfer is very much on hold for now.
The club have a number of concerns about Nusa's fitness after his medical raised issues.
Brentford are asking for medical documentation regarding Nusa from both Club Brugge and the Norwegian Football Federation.
While he is linked to other clubs, such as Tottenham and Chelsea, this news may give other teams pause as well.
