As per UEFA broadcast rules, the first 15 minutes of the pre-match session are open to the press and there was encouraging news from the session at Carrington.
Harry Maguire was involved after missing the weekend’s match with Tottenham Hotspur due to a minor knock he’d picked up in training.
Kobbie Mainoo also trained ahead of the trip to Portugal and that’s positive news for supporters, after the Academy graduate was substituted with an apparent injury against Spurs on Sunday.
Meanwhile, Mason Mount missed training as a precaution following the head wound that he sustained at Old Trafford.
