I think Sarri needs to change style of play for games away from home when we don't play a full strength team. It's all very well us trying to be Barcelona but unfortunately last night we looked like Wenger's Arsenal at the back, soft. Can see what he's trying to do. We should Keep the 4 3 3 but change tactically, put Kante as a defensive midfielder and play with quick transitions, concede possession and play on the counter attack.
First goal too easy to get a shot off and should have been saved. Second goal, Christensen mistake with a simple square ball and generally terrible from us. Don't think Willian was fouled either. Referee was pretty awful at times generally though, that is the premier league though. Morata and Willian should have penalties though for me. In any other European leagues at least one of those would be given and probably a red / yellow card as well.
Sarri needs to adapt to the league, lots of teams are physical and get away with playing in a way that you can't in any other country. Needs to adapt to it. When we play Brighton away unless we have our complete team available to play Barcelona style we should change tactically.
