Former Man United star's Barcelona form gives Ruben Amorim buy-back clause decision

Manchester United may have a decision to make on one of their former stars before the January transfer window closes.

United have until February 3 to complete their transfer business. Several players have already been linked with a move to Old Trafford, but it remains to be seen if any new signings are made before the deadline.

Left-back has been an area of the squad deemed to be a priority for strengthening during the January transfer window. Ruben Amorim currently has Luke Shaw and Tyrell Malacia as the recognised left-back options in the squad, with Diogo Dalot often performing in the role.

Lecce's Patrick Dorgu and Bournemouth's Milos Kerkez have been identified as targets for United this month. One player who may be of interest to United is one who only left the club less than 12 months ago.

Fernandez starred for Benfica in the Champions League on Tuesday night despite being on the receiving end of a 5-4 defeat. The 21-year-old provided the assist for Vangelis
