Barcelona trained on Monday afternoon and held a minute’s silence at the start in memory of the victims of the Paris terror attacks.
Lionel Messi was with the group as he continues his comeback from his knee injury. Ivan Rakitic was also back, having picked up a calf injury on November 4.
Marc Andre ter Stegen completed the returns, because he was given leave last week so he could have dental surgery.
The squad was without the players on international duty, who are mostly set to return on Wednesday and Thursday.
Barcelona’s next session is Tuesday morning at 11am CET.
