#1 3-4-3 to the rescue
Alex Oxlade-Chamberlain on the right wing was easily the best player on the pitch by a mile. The Englishman took the right wing-back position like a duck to water and ensured that his side always have an option going down the touchline.
With his natural pace and strength, the side looked more solid going forward. While this was the first time since 1997 that Arsenal played a 3-4-3, it always looked like a work-in-progress – something that was visible in the way the team looked lost trying to deal with Alvaro Negredo scoring his goal.
Arsenal were amongst the last few sides in the Premier League yet to work in a 3-4-3 system but this match further strengthens the argument that the more defensive formation is here to stay.
