Summer signing Thomas Partey was hard at work once again with his new team-mates, and will be pushing to start on Sunday evening after making his full debut for the club in midweek.
The Ghana midfielder drew plenty of plaudits for his performance in the 2-1 Europa League win at Rapid Vienna on Thursday.
Arsenal captain Pierre-Emerick Aubameyang has been impressed by the former Atletico Madrid player at the training ground, saying: "Thomas has been great since joining the club.
"He has integrated so well in the squad. He is kind, calm and smiley. On the pitch, we have seen already seen what he will bring us in matches.
"My family is from Gabon but I also have some roots in Ghana where Thomas is from so we are family too!
"It is good for some of our younger players as well to have a player like him, of his calibre at training. They will learn a lot from him."
