Sporting Lisbon will reportedly attempt to raise the release clause of Bruno Fernandes from £86.5m to £129.8m ahead of a potential summer bid from Manchester United.
Fernandes is enjoying a brilliant 2018-19 campaign, finding the back of the net on 28 occasions and also contributing 15 assists in 47 appearances in all competitions for his Portuguese club.
Fernandes's current deal includes a release clause of £86.5m, but according to Calciomercato, Sporting are keen to commit the midfielder to a new contract which will raise the buy-out figure to £129.8m.
The Portuguese joined Sporting from Sampdoria in 2017 and has helped the Green and Whites land two Taca da Liga crowns during the last two campaigns.
Paris Saint-Germain, Juventus and AC Milan are also believed to be considering a summer bid.
