- Arsenal have notched up a third away win this season.
- The boss deployed a 3-man defensive unit, consisting of Kieran Tierney, Rob Holding and Shkodran Mustafi.
- Arteta says he aims to adapt the players' roles depending on an opponent's strengths and weaknesses.
- The boss adds that he wants to achieve more tactical flexibility with this squad.
At the post-match press conference, the boss was asked to explain his choice of a 3-man defence instead of a usual 4-2-3-1 formation.
"We will change the game plan in relation to what we want to generate attacking-wise and as well how we can constrain the opponent and how we can better control their strengths," Mikel Arteta replied as quoted by Arsenal's official website.
"As well, with the players we had available it was the best fit for everybody to play in their position and be more comfortable, more secure about their jobs.
"We don't have the flexibility that I would like right now to change more things, but it's part of the process."
Arsenal have racked up their third victory on the road this season - all under 3 different managers. The first one was achieved in the first game of the season against Newcastle [1-0] when Unai Emery was at the helm.
This win lifts us to ninth with 7 more games left to play.
