Arsenal maintained their 100% start to the Europa League with a comfortable 4-2 victory away at Bate Borisov on Thursday night.Despite making nine changes to the team that beat West Brom, the Gunners' fringe players stepped up to ensure they avoided what would have been a big upset in Belarus.Theo Walcott grabbed a brace while Rob Holding scored his first Arsenal goal and Olivier Giroud notched his 100th for the club from the penalty spot.Goals from Mirko Ivanic and Mikhail Gordeychuk did give the home fans something to cheer in a game full of defensive errors.Nevertheless, there were still plenty of positives Arsene Wenger can take back to the Emirates as Jack Wilshere impressed once again and a number of youngsters were given a rare opportunity too.There was one slightly awkward moment for the Arsenal boss after the final whistle, though.As you can see below, the camera panned to Wenger as he made his way from the touchline to the tunnel.One plucky ball boy gets his phone out and appears to ask the Frenchman for a selfie.To his credit, Wenger was about to oblige, only for a Bate official to pull the ball boy away and warn him against taking the photo. Very harsh!Meanwhile, having stopped for the selfie, Wenger was left looking a little uncomfortable as he tried to walk away as if nothing had happened.

Even when Wenger is trying to be nice he's made to look a little silly - not that it will dampen his mood this evening, though.

Three games this week was always likely to be a tough challenge for Wenger's men, however, two wins from two suggests the Gunners might have a bit more squad depth than critics give them credit for.

They return to action on Sunday with a home clash against Brighton in the Premier League.
