Manchester United trio Harry Maguire, Kobbie Mainoo and Bruno Fernandes will have to tread carefully when Leicester City visit Old Trafford in the fourth round of the FA Cup on Friday night.
United booked a fourth round date with the Foxes after beating Arsenal on penalties in the third round at the Emirates Stadium last month. The contest had finished 1-1 after 120 minutes but United prevailed on spot-kicks, winning 5-3.
United produced a heroic defensive display in the capital after having Diogo Dalot sent-off for a second bookable offence with 61 minutes on the clock.

Having dispatched as one of the favourites to win the FA Cup this season at the first hurdle, United will have ambitions of going the distance in this season's competition and retaining their crown after beating Manchester City 2-1 in last season's final.
However, if United do progress to the fifth round with a win over Ruud van Nistelrooy's side, Maguire, Mainoo and Fernandes will each have to watch themselves after earning a yellow card apiece against the Gunners.
FA Cup rules state that any player that plays for a club that enters the competition in the third round must serve a one-match ban after being awarded two yellow cards. The cut-off point is not until after the quarter-final stage.
It means Maguire, Mainoo and Fernandes will each have to watch their step against the Foxes to avoid being suspended for a potential fifth round assignment. Lisandro Martinez was also booked against Arsenal, but he is expected to have a lengthy spell on the sidelines after sustaining a knee injury in Sunday's 2-0 defeat to Crystal Palace.
Dalot earned two yellow cards that led to a red against Arsenal, meaning he had to serve a one-match ban in United's following game, resulting in him missing the 3-1 win over Southampton four days later. A caution for him against Leicester would not see him banned for United's game in the fifth round should they make it through.
