Cedric Soares returns to the Arsenal starting line up for their Premier League clash with Manchester United at the Emirates Stadium.
The Portuguese international replaces Rob Holding in the only change to the starting XI that beat Chelsea 4-2 at Stamford Bridge in midweek.
However, with another full back in the squad it's safe to assume that the Gunners will be returning to playing a back four for this crucial clash in the race for the Champions League, rather than the hybrid back three/back four defence they had on Wednesday.
