Ruben Amorim could restore Manchester United first-teamers who have only played 45 minutes together

Ruben Amorim takes charge of Manchester United at Old Trafford for the first time tonight against Bodo/Glimt in the Europa League.

Amorim played at Old Trafford in successive seasons with Benfica and Braga in the Champions League back in 2011 and 2012 and tonight's tie is the first of two home fixtures this week, with Everton visiting on Sunday.

Kobbie Mainoo has been sidelined for nearly eight weeks and was completely unused on Sunday. Manuel Ugarte seems to be a consistently late arrival back from international duty, which ensured he started on the bench at Portman Road.

United could start one centre half in their back three. Shaw is an option at left centre back, with
