Arsenal were hard at work ahead of their Premier League clash against Manchester United.
The Gunners have the chance to move up to third in the table if they win away at Old Trafford on Monday night.
And competition for places is heating up with the return to action of Rob Holding, Kieran Tierney and Hector Bellerin.
The defensive trio made their first-team comebacks against Nottingham Forest in the Carabao Cup, beating the Championship side 5-0.
Konstantinos Mavropanos is also pushing for a first appearance of the season for the first team after a groin strain kept the centre-back out for much of the 2018/19 season.
The 21-year-old has been back playing for the Under-23s side along with Bellerin and Tierney in recent weeks, and while he did not make the final squad against Forest, his shirt was hanging in the dressing room.
However, he and Bellerin are unlikely to feature in the trip to Old Trafford after starting again for the Under-23s in their 2-2 draw against Liverpool on Saturday.
But Holding and Tierney look like making the trip to Manchester after being left out of the Premier League 2 game.
Alexandre Lacazette remains out with an ankle injury, but Pierre-Emerick Aubameyang has been in fine form in his strike partner's absence.
