Nicolas Pepe took part in his first group session since joining us from Lille earlier this week.
The Ivory Coast winger lined up alongside new team-mates Pierre-Emerick Aubameyang, Matteo Guendouzi and more on Friday, ahead of Sunday's Joan Gamper Trophy clash with Barcelona, which UK viewers can watch LIVE on Premier Sports.
Lucas Torreira, who returned to training this week, also took part. Our club photographer was there and sent back these pictures:
