He won't be doing that again then. Maybe all teams should do that - hold your head, subbed. Going down for 'head injuries' to waste time would disappear overnight.Especially as from his body language it looked like he was trying to tell the physio he was just holding his head to stop play/make it look worse but without saying that.
I think we're also a bit more willing to boot the ball out rather than try and keep possession for possession's sake as we did to our cost a few times last season.One change i've noticed is that we're playing offside trap a lot. Caught Everton offside probably 6+ times now
