William Saliba returns to the bench as Arsenal take on Slavia Praha in the UEFA Champions League.
The French centre-back has missed the entirety of the campaign so far after suffering a back injury while playing for France in the semi-final of the World Cup against Spain.
It was initially feared that the 25-year-old defender could miss far more of the season, however, he returned ahead of schedule.
Victory tonight will take the Gunners back into the all-important top eight of the league stage; far above their Czech opponents.
Slavia Praha have struggled so far in Europe, losing two of their three Champions League games. It's a complete contrast domestically though, Jindřich Trpišovský's side are unbeaten and top of the Czech first division.
