Manchester United have made a firm move for Barcelona defender Marcos Alonso.

Needing to find a new left-back signing before Friday's transfer deadline due to an injury crisis, United are making a serious move for Alonso.

Marca says a two-year contract has been tabled by United to Alonso.

And Barca would be willing to allow Alonso to leave with the Spaniard yet to be registered with LaLiga due to Financial Fair Player issues.

Alonso joined Barca a year ago from Chelsea.
