But the point here is about flexibility. Sure, Fergie's United were known for their wing play but it wasn't his do-or-die approach. His team carried threat from midfield as well and there were times when he tweaked it and heck, he even played the diamond midfield system from time-to-time. As for Conte, we all know he likes the back 3 system but at the same time, we all know the severe limitations of that system. When it doesn't work out, as we saw many times last season, he rarely tries to change things around. Not saying Sarri's football has gone to pots that he needs to make a wholesale change but surely, it wouldn't hurt to make some minor tweaks if/when needed, would it?
