5 things we learned from Arsenal's defeat to Manchester City

#4 Lichtsteiner will do exactly what he was bought for

The right-sided defender played on the left on his debut

With regular left-backs Sead Kolasinac and Nacho Monreal injured, it was left to youngster Ainsley Maitland-Niles to deputise. But when he suffered an injury 35 minutes into the game, new signing Stephan Lichtsteiner, a right back by trade, had to come on in his place.

He was bought to give Hector Bellerin a bit of competition on the right side of defence and maybe play the odd game in the Europa League and Carabao Cup. At 34, he isn't supposed to set the world alight, but instead provide solid cover and a workmanlike attitude. Largely keeping Riyad Mahrez quiet he did precisely what it says on the tin.

He hopefully won't have to play on the left many more times, but he showed enough to vindicate his signing as a backup right back.
