I'm not saying we should do it for 90 minutes or not even every game - it would be good to see a "plan b" against these types of defenses though because we just don't have the height to do anything with crosses against what it as times 11 men behind the ball.
Here's just one example from last night:
Southampton have every man in their own box (this was just after Sterling's miss that went wide) + our guys makes 16 players in a very small space... but it happened a lot and has happened a lot against defensive teams this season...
It may not be the answer - I don't know, it's just a suggestion / idea because we have been frustrated by these defensive "walls" quite a bit this season and this constant pressing and pushing teams back just doesn't seem to work all the time...
