Louis van Gaal has a selection dilemma at full-back for Manchester United’s Europa League showdown against Liverpool on Thursday.

Ashley Young and Cameron Borthwick-Jackson trained on Wednesday morning after injury absences to give Van Gaal a sudden wealth of options as United attempt to overturn Liverpool’s two-goal advantage in the last-16 tie.

With Antonio Valencia and Matteo Darmian recently back after spells on the sidelines, six players could be available for the full-back positions.

Guillermo Varela has been the regular right-back for the last month, while Marcos Rojo has started five consecutive matches at left-back.

Both are regarded by Van Gaal as strong offensively, although Borthwick-Jackson, 19, had particularly impressed at left-back before he got injured in last month’s FA Cup win over Shrewsbury.

Converted wingers Young and Valencia offer experience, while Darmian had been the manager’s preferred choice at right-back in the first half of the campaign.

Young, who has been out since January with a groin injury, and Borthwick-Jackson were pictured taking part in training on Wednesday morning and Van Gaal will provide an update on their potential availability at his press conference at 3.30pm.

In other Manchester United team news, Bastian Schweinsteiger, Morgan Schneiderlin and Juan Mata could be restored to the starting line-up at Old Trafford on Thursday night.
