The Arsenal manager is likely to be forced into at least one change for Saturday's Premier League clash at home to Everton after Bukayo Saka limped off after 10 minutes in the 2-2 Champions League draw against Bayern Munich in midweek.
“We lost Bukayo, who actually was having a great game," Arteta said. "They are a bit concerned. A player that has to come off with a really sharp pain is never good news but we have to wait and see."

Though, with Christos Tzolis also doubtful with a hamstring injury, there may be space in the matchday squad for an additional attacking player alongside wonderkid Max Dowman.
He can, however, feature in the Premier League and, significantly perhaps, the Arsenal U21’s are also in action on Saturday so it remains to be seen which squad he is part of.

Scanlon, capped 28 times at senior international level by Gibraltar, has been a regular for the Arsenal U21’s, registering three goals in four Premier League 2 appearances.
“I like to score goals, assist, so hopefully I can excite players who watch me,” he said upon joining the Gunners from Man United in the summer transfer window.
“I’m looking forward to playing, representing the badge, improving and hopefully showing people what I can do.”
