Overview
- Reporting indicates Mikel Arteta could include academy striker Andre Harriman-Annous for Slavia Prague in what would be a first Champions League appearance.
 - A journalist’s training update noted no sign of Viktor Gyokeres, Kai Havertz, Gabriel Jesus, Noni Madueke, Gabriel Martinelli or Martin Odegaard, while Harriman-Annous trained with the first team.
 - With Martin Zubimendi suspended, Mikel Merino is likely required in midfield, reducing senior options up front for the Prague match.
 - Harriman-Annous scored 13 times in 17 U18 matches last season and logged 77 minutes on his senior debut in the League Cup against Brighton last week.
 - Arsenal have opened the European campaign with wins over Athletic Club, Olympiacos and Atletico Madrid and now seek a fourth straight group-stage victory.
