The 22-year-old has had three sublime performances since the Liga NOS restart, scoring in Sporting’s last two games.
There is also interest from England, with O JOGO claiming the ‘majority’ of Premier League clubs have asked about him.
Sporting had been willing to negotiate at €15m until recently, but the interest has led them to lift their valuation.
The Lisbon club have not set a fixed price but have tasked agent Jorge Mendes to find a buyer.
Mendes is well-placed in English market and has already sounded out several clubs about potential deals for Cabral.
Cabral feels ready to make the move to a bigger league and his unique talents appeal to many clubs.
The Cape Verde international has made 11 league appearances this season, with three goals and three assists to his name.
While his next club isn’t known, what is for sure is that Cabral should now earn Sporting more than the €15m they anticipated.
