Manchester United have reportedly been keeping an eye on Porto winger Yacine Brahimi with a view to a possible summer switch.
According to Joe Bernstein of the MailOnline, Red Devils boss Jose Mourinho wants to add a "world-class left-winger" to his current squad. Brahimi is said to have been considered as an option, although it's noted the Algeria international has a whopping £51 million release clause in his current contract.
"If United are to pursue their interest further, there would be question marks over the future of Anthony Martial who has impressed in patches this season without winning the full trust of Mourinho," added Bernstein.
