Arsenal's French international centre-back William Saliba returned to training with the Premier League champions on Tuesday for the first time this season.
Saliba has not played since injuring his back at the World Cup in July.
But on Tuesday he took part in Arsenal's training session at their London Colney centre as the squad prepares for Wednesday's Champions League clash away to Slavia Prague.
During the close season, Arsenal signed England centre-back Ezri Konsa from Aston Villa, who has settled in well alongside Gabriel Magalhaes in the centre of defence.
Despite his return to light training, Saliba is unlikely to feature for Arsenal in Prague, or be called up by France coach Zinedine Zidane for his country's Nations League matches against Italy and Turkey later this month.
