Exactly... My point has always been that it's not just simple adjustments here and there that scores against bunkering. It's the entire reason that teams bunker in the first place. I don't believe any coach knowingly likes to bunker. They do it because they know they can't beat the other team by playing so they try to simplify the game, limit great chances, and hope to hell that they score on one of their few chances. I love that we never bunker. It's awful to watch.
But also agree big time that the biggest way to beat it is to do well on set pieces. When teams bunker against us, we always get a bunch of corners. Must find a way to score on a higher percentage of those corners. Problem is we don't really have the best guys in the air. Long is OK, and Parker is really good. Beyond that, no good options outside of Collin when we play the 3 man back line.
Leicester won the prem with a very deliberate bunker-and-counter strategy. Mourinho isn't far off from that approach this season with Man U.
