Arsenal and Man Utd have been told to pay the release clause or forget about signing reported target Vitinha this summer.
The Premier League duo have been linked with a move for the FC Porto star this summer, with both keen on bolstering their midfield options ahead of the new campaign. The Red Devils need replacements for Paul Pogba and Nemanja Matic, with the pair having departed this summer.
Meanwhile, Arsenal boss Mikel Arteta is keen to add more bodies in the centre of the park having not yet managed to find a natural partner for Thomas Partey. Vitinha could potentially be an excellent candidate for that role having enjoyed a productive season in Liga NOS.
