Speaking to BBC Sport, Garth Crooks said: "To beat Arsenal took a superb team performance by Aston Villa from start to finish and it was a wonderful return to Emirates Stadium for manager Unai Emery.
"His team couldn't have performed any better. Villa carried their tactics out to the letter and it started with Emiliano Martinez. Playing out from the back, and when Arsenal are pressing, you have to have nerves of steel.
"Martinez remained unshakeable throughout this entire fixture. His point-blank save from Leandro Trossard at a crucial stage in the match was a turning point in the game and Villa never looked back."
Martinez ended up making BBC's Premier League Team of the Week for his display at the Emirates while not a single Arsenal player was included.
The 2022 World Cup winner was allowed to leave the Gunners by Mikel Arteta who has since gone through three first-choice goalkeepers at the club.
