Wenger's League Cup debutants: Vela to Van Persie, Sunu to Cesc
Arsenal 6-1 Coventry: 26 Sep, 2012
Gunners trounce League One side with goals from Giroud, Oxlade-Chamberlain, Arshavin, Walcott (2) and Miquel.
Damian Martinez: The Argentine keeper is still contracted to Arsenal, and appeared in the infamous 7-5 victory over Reading in 2012/13. Previously enjoyed loan spells at Oxford United, Sheffield Wednesday and Rotherham, and is now net-minding at Wolves for the 2015/16 campaign. Unlikely to make an impact in Wenger's first team with Petr Cech and David Ospina ahead in the pecking order.
Martin Angha: Joined Arsenal from FC Zurich in 2010 and made his debut here, where Arsenal were rarely tested. Left the club this summer and joined FC Nurnberg in the Bundesliga, but didn't make a huge impact for the German side and dropped down a division to 1860 Munich in 2014/15 where he counted former Gunner Volz as a team-mate. Joined St. Gallen in his native Switzerland this summer.
Serge Gnabry: The German's debut here was quickly followed by his Premier League bow within a month. The explosive youngster is still hoping to become a fully fledged member of the first team after a bright start, before a bad injury hampered his progress. Looking to make an impression on loan at West Brom this year.
Reading 5-7 Arsenal (aet): 30 Oct, 2012
A bonkers game where Arsenal rally from 4-0 down after 37 minutes to storm back in the most dramatic fashion. Walcott grabs hat-trick.
Thomas Eisfeld: The solitary signing of another barren transfer window for the Gunners in January 2012 from Borussia Dortmund, Eisfeld made his bow with half an hour remaining at the Madejski Stadium. He didn't play again until the following season, where he grabbed another pair of League Cup outings (and scored at West Brom), but never established himself and joined Fulham permanently in 2014/15. Failed to make his mark at Craven Cottage, though, and after a loan spell with German second-tier side Bochum, joined them permanently.
Jernade Meade: The pint-sized left-back hasn't made a league appearance for any club, despite joining Swansea's development squad in 2013, then being loaned out to Luton. He has, however, a Champions League start under his belt from 2012/13 against Olympiakos (who else?) after this 15-minute extra-time cameo at Reading. In 2014, joined the Spartan South Midlands Football League's Hadley, bossed by former Chelsea man Micky Hazard.
West Brom 1-1 Arsenal: 25 Sep, 2013
Berahino cancels out Eisfeld's second-half strike but Arsenal advance on penalties.
Isaac Hayden: Despite coming through the youth team as a centre-back, cultured youngster Hayden made his debut here as a central midfielder for the injured Mathei Flamini. He wouldn't play again for another year, this time in his natural position against Southampton, but is yet to play in the Premier League for Arsenal. Joined Hull on a season-long loan this summer, where he's enjoying regular football.
Hector Bellerin: Former Barcelona product Bellerin made an inconspicuous start to his Gunners career with a substitute appearance at The Hawthorns, before impressing on loan at Watford in the Championship. The marauding right-back finally got his big break last season when he was chucked in at the deep end against Borussia Dortmund in the Champions League, but later stood in for the injured Mathieu Debuchy and hasn't lost his first-team place since.
Kristoffer Olsson: Replaced fellow youth team graduate Hayden and scored in the shoot-out, but this was the young Swede's sole Arsenal appearance. Joined FC Midtjylland on loan almost a year later and made the move permanent just over two months later.
