Nottingham Forest may be on the hook for a big payment for goalkeeper Odysseas Vlachodimos.
The 29-year-old was a deadline day signing for the Premier League club from Benfica in Portugal.
While he is signed as a likely no.2, Radar states that Forest may have to pay as much as 10 million for him eventually.
Given the deal was done so late in the window, Benfica wanted a higher fee to agree to a sale.
Forest eventually agreed to their terms, with owner Evangelos Marinakis very eager to add a Greek player to their squad.
Vlachodimos will be hoping that he can use this opportunity to compete for a starting spot.
