Arsenal travel to the Hawthorns in the third round of the Capital One Cup tonight in what represents a tricky tie against West Brom.
There are several players missing from the squad, meaning members of the youth team are likely to get their chance to shine.
With Tomas Rosicky yet to recover from an injury sustained on international duty, German youngster Thomas Eisfeld may start in an advanced role, with Mesut Ozil likely to be rested.
Following on from his impressive display against Stoke at the weekend, Serge Gnabry is heading for his second start in just three days for the Gunners with Japanese international Ryo Miyaichi on the opposite flank.
On Gnabry, Arsene Wenger told Arsenal Player: "It's a fantastic opportunity for him. He can play right or left or even behind the striker.
"He can even play as a striker. I believe against Stoke what I liked in his game is that he grew through the game, he became better and better."
The story of the night goes to Nicklas Bendtner, however, who returns to the Arsenal XI after a two year absence.
There is also a place in the squad for forgotten man Park Chu-Young, who will make his first appearance on the team sheet in over a year.
Thomas Vermaelen is in line for his first start of the season after recovering from a back injury that kept him out for most of pre-season.
Expect Per Mertesacker to fill in alongside him as Carl Jenkinson and Nacho Monreal fill in on the flanks.
Tonight could see a debut for deadline day signing Emiliano Viviano, but Lukas Fabianski may be preferred.
Arsenal predicted starting line-up:
Viviano, Jenkinson, Mertesacker, Vermaelen, Monreal; Flamini, Arteta; Eisfeld; Gnabry, Ryo, Bendtner
