You know what I dont get about Arteta's Pulisball tactics is that, yes, trying to gain the margins from corners and time wasting and being nasty to play against is understandable, as I have seen it before many times. However, even the most fervent fan will tell you that sitting back and not pressing the advantage against relegation fodder or lower league teams, despite how good your defence is, will just inevitably invite trouble.
Id understand not having the players or trying to manage the first team 11, but when you comfortably have the best squad in the league its absurd to play this way, especially when they have the quality in the side to play decent football.
