Kieran Tierney made his Arsenal return as the Gunners thrashed Charlton 6-0 in a closed doors friendly.
The former Celtic man became the most expensive Scottish player of all time when he moved to the English club last summer.
Since then he's struggled with injury, making just four Premier League starts.
Tierney hasn't played competitively for Arsenal since December 9 thanks to a shoulder injury, but he made his return on Saturday afternoon.
The Scotland international was part of a team that thrashed fellow Londoners Charlton Athletic 6-0 at the Emirates.
Eddie Nketiah scored a hat-trick and strikes from Alexandre Lacazette, Pierre-Emerick Aubameyang and Joe Willock completed the rout.
Last month manager Mikel Arteta laid out his plans for Tierney after his difficult start to life in England.
He told Ian Wright as part of an Adidas event: "I’m really looking forward to working with him and giving him the opportunity to play. His attitude, his commitment, his willingness, it’s incredible.

"I think he’s going to bring something special to us. It [the injury] has been a shame, but it’s part of his development. During your career, you go through these moments.
"I challenged him to say, 'Kieran, how are you going to react to that? You can’t feel sorry for yourself, this happened.
“'Okay, the level of pressure now is a little bit higher, you have to deal with it, you’re playing with a top club, top expectations, deal with it. You have everything to be successful here.
“'You have the best possible attitude that I’ve known from a player, go and live your profession and enjoy it, and that's it.'”
