Arsenal players were back on the training pitch before Sunday's Premier League clash at home to Chelsea.
The Gunners suffered a miserable 2-0 defeat at Brentford in the opening game of the new season on Friday.
Ben White, a £50 million ($68.7m) summer signing from Brighton, was one of several Arsenal players who endured a night to forget at the promoted Bees.
There was no sign of captain Pierre-Emerick Aubameyang or fellow striker Alexandre Lacazette at London Colney on Tuesday — the pair missed Friday's match due to illness — or Thomas Partey and Gabriel, who were also absent at the Brentford Community Stadium.
The humbling defeat has turned the spotlight on manager Mikel Arteta who faces a battle to get points on the board in the next two matches.
Up first are Chelsea, who won their first game 3-0 against Crystal Palace and should have £97.5m signing Romelu Lukaku in their squad for the match at the Emirates Stadium. Then it is reigning champions Manchester City at the Etihad Stadium on August 28.
In between those games, Arsenal face a tricky League Cup tie away to Championship side West Bromwich Albion. All in all, a tough start to the new campaign for the Gunners.
