Arsenal travel to Camp Nou to face Barcelona for the Joan Gamper Trophy tonight, but club-record signing Nicolas Pepe will not feature.
Pepe completed a £72million transfer from Lille on Thursday, but will not make his debut for Unai Emery's side today after being left out of the 21-man travelling squad.
With Emery not short of attacking options, the 24-year-old winger is more likely to feature in the Gunners' Premier League opener at Newcastle on 11 August
Alexandre Lacazette has also been left out as he recovers after suffering a sprained ankle in the defeat by former club Lyon.
Lucas Torreira is back in contention following an extended break after Copa America, while Real Madrid loanee Dani Ceballos could be named in the starting lineup having been omitted from the squad to face Angers.
Laurent Koscielny's stand-off with Arsenal continues, while Hector Bellerin, Rob Holding, Konstantinos Mavropanos and Emile Smith Rowe are still sidelined.
Mesut Ozil and Sead Kolasinac return to the squad after the pair missed the matches against Lyon and Angers having been targeted in an attempted car-jacking last week.
As for Barcelona, Luis Suarez is back in training but Lionel Messi has yet to return from his post-Copa America break.
Gerard Pique has also resumed training after missing the win over Vissel Kobe.
Malcom, meanwhile, has travelled to Russia to complete formalities ahead of his move to Zenit St Petersburg.
