3 at the back has not worked for us for almos 20 years for some reason many have tried it but it always a disaster, constant choping and changing is a sign of despeation, I remember on sherwoods run to the sack He said “I’L keep chopping and changing till I get it right” I’d like to think Smith knows what he's doing and not chopping and changing formations for the sake of it but at the same time I do agree he is way to stubborn with the 4-3-3 ,we had an identity last season dont know where its gone
