KingslandBarge I agree with the observations, however I would tend to think all the teams in or around the top 4 will face a low block in most of their games, and would need to figure out how to overcome it. City, Liverpool, Newcastle?, ourselves. In my opinion (eye test, haven't looked for supporting data), our football is the least appealing of all the top teams, and probably our xG for/big chances created is lowest.
We play like a Mourinho managed team back when he was a half decent manager. Arteta is doing similar things when it comes to man management (poor), resource management (a tad excessive, even though I don't really care about this), and choice of football style (focused primarily on defensive and midfield stability and a heavy reliance on brilliant wingers think Damien Duff/Joe Cole/Arjen Robben).
We are winning the tight games right now, but if we continue like this, the moment we hit a skid and are not able to score goals or win games and the boys begin to tire or lose confidence, then it's all going to come crashing down.
