In all seriousness I think the lesson is that we rely heavily on a McCarthy/Besic type to run around getting stuck in. We don't defend well as a team and it puts a lot of pressure on whoever is in that role. Our defensive implosion timed perfectly with McCarthy's injury (we were winning at Bournemouth, he got injured, it finished 3-3... then the long run of throwing wins away ensued). Up until Besic came into the team and we settled a bit with some good away performances.
We need to defend better as a team. We don't press and I think it's clearly a tactical decision not to. It puts a big burden on whoever is next to Barry (who breaks up play well himself) and when that duty falls to someone other than Besic/McCarthy, we're exposed badly.
Weirdly enough, we did press a bit more last night. Probably with the legs of Lennon and Cleverley on the wings it helped.
