Manchester United are being linked with Porto midfielder Yacine Brahimi.
Correio da Manha says United have approached Brahimi, 29, who plays on the left wing.
The attacker comes off contract at Porto in June.
Everton and Wolves are also interested in Brahimi, who is now free to negotiate pre-contract terms with foreign teams.
For their part, Porto haven't given up on securing the midfielder to new terms.
