Barcelona are reportedly looking at three options as back-ups for Jordi Alba at left-back, a position where a lack of depth has become a concern for the club.

Lucas Digne and Marc Cucurella left in last summer’s transfer window, leaving La Blaugrana thin at the position.

Right-backs Sergi Roberto and Nelson Semedo have both deputised for Alba on occasion this season, as has academy graduate Juan Miranda, but none of those players have convinced.

Now, Mundo Deportivo are reporting that Barcelona have identified Lyon’s Ferland Mendy, Atletico Madrid veteran Filipe Luis, and Real Betis’ Junior Firpo.

The 23-year-old Mendy will have a chance to impress Barcelona in the coming weeks, as the Catalan club face Lyon in the Champions League round of 16.

Firpo reportedly has a €50million release clause, making him a difficult transfer target, though Barcelona’s good relationship with Betis could make negotiations smoother.

Luis, of course, has been a stalwart for Atletico, and has proven pedigree in La Liga.
