#4 Utilising their Plan B more often
Arsenal's 2-0 victory against Manchester City last season, they're 2-0 win against Bayern Munich in the UEFA Champions League group stage this season showcased their ability to play the unorthodox but ultimately win. They weren't the same Arsenal. They sat back, they dug deep and hit the teams on the counter.
Why is it the Gunners don't do this more often? No way am I suggesting Arsenal become a Chelsea or an Atletico Madrid but when teams play two banks of four to prevent the creative players from getting between the lines, the team have to adapt, let them have the ball, tempt them to attack more and then attack on the counter.
While they use this strategy against the 'bigger' teams, they ought to start using it against the teams who counter their slick passing style. Arsenal are at the edge of being found out by every team in the League and in Europe. The likes of Tony Pulis and Alan Pardew have easily decoded Arsenal's game and have been able to effectively counter the style with the use of their physical players.
