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.
