Gabriel Jesus scored 90 seconds into his first Arsenal outing as his double helped the Gunners to a 5-3 comeback victory over German second division side FC Nurnberg.
The Brazi striker, who completed a £45m move from Manchester City earlier in this summer transfer window, came on at half-time in Germany with the Gunners 2-0 down – and made an immediate impact, scoring high in the net from Ainsley Maitland-Niles’ pass.
Mohammed Elneny then hit a wonder-strike to equalise for Mikel Arteta’s side, before two Nurnburg own goals from Christpher Schindler and Tim Handwerker gave the Gunners a 4-2 advantage.
Jesus then finished Gabriel Martinelli’s cross at the front post with 15 minutes to go to add a fifth for Arsenal, just after Lukas Schleimer pulled one back for the German side.
Arteta named a strong starting line-up for this pre-season outing, with Emile Smith Rowe, Nicolas Pepe and Kieran Tierney among the starters – but their warm-up game fell into disaster.
Johannes Geis and Kwadwo Duah scored past new Arsenal goalkeeper Matt Turner in the space of five first-half minutes to stun the Premier League side.
Arsenal are likely to welcome back their international players – including Bukayo Saka, Aaron Ramsdale and Martin Odegaard – next week before their tour of the United States.
