The return of William Saliba from his loan spell with French side Marseille has been like a big-money signing for Arsenal. Saliba has been rock solid at the back for Mikel Arteta's side this season and has warranted himself a place in the France World Cup squad alongside the likes of Kylian Mbappe, Karim Benzema and Raphael Varane.
His breakout campaign came last season, helping guide Marseille to Champions League football and winning himself the Ligue 1 Young Player of the Year award. There were rumours linking him with another short-term departure in the summer but Arteta was quick to refute them and has started him in all 14 of the Gunners Premier League games this season.
Saliba has established himself as one the league’s most impressive defenders and has been part of Arteta's backline that has kept the joint-most clean sheets this campaign. The north-Londoners sit top of the table after enjoying their best start to a Premier League season, winning 12 of their opening 14 games.
