Manchester United have reportedly asked Barcelona about the possibility of signing Marcos Alonso after losing Luke Shaw to injury.
The Red Devils are short of options at left-back, with the England international expected to be out for some time.
Back-up defender Tyrell Malacia is also sidelined, while the Red Devils have also sent Brandon Williams out on loan.
The Telegraph reports that United have asked Barcelona about Alonso and are also interested in Sergio Reguilon and Marc Cucurella.
Alonso has yet to feature for Barca this season but was registered ahead of Sunday’s match against Villarreal in La Liga.
