Benfica want to keep hold of Wolves striker Goncalo Guedes.
The Portugal international is on-loan at Benfica after joining in January from Molineux.
While he has undergone knee surgery, Guedes is still wanted by Benfica in a permanent deal. This despite no such option being included in the deal.
As such, Benfica and Wolves will have to negotiate fee for the striker.
Wolves are expected to seek 30m to sell Guedes this summer.
