Midfield – Elneny, Odegaard, Xhaka
Mohamed Elneny gave a solid account of himself against Chelsea on Wednesday and his experience could convince Arteta to give him another shot, instead of Albert Sambi Lokonga, against United. Granit Xhaka is sure to take the other defensive midfield place, although Gunners fans will keep fingers crossed that his infamous temperament can be kept under control during such an important match.
Martin Odegaard continues to impress in an advanced central role, and he notched another assist at Stamford Bridge. That was his 10th goal contribution in the league this season, and in terms of chances created he is right up there with league leaders Trent Alexander-Arnold, Kevin De Bruyne and James Ward-Prowse.
