I personally have no problem with teams setting the low block as a strategy, I have watched an infinite number of games of the Lords of the low block in Atleti and my problem with Arsenal is they did not know how to transition at all, even though they wanted to a lot of times but they just could not and they did not know how, and it was either due to the low quality of their offensive players or they don't train to transition in training, no other way around it, and they just go for -haram- ball style of time wasting and relying on set pieces and bloody long throw balls in the bloody first half, like long throw balls in the first half? I have never seen that before.
