This is true. I think alot has come down to the players in our squad over the years tho...
We have had players who lets be honest moyes gets the best out them. Your osmans, hibberts, cahill's ect's are not top quality players who believe they are winners. We'v always lacked game winners aswell.
I truly believe looking at the squad now we not only have game winners but in players like Gibson fellaini pienaar mirallas jelavic Heitinga Baines jags Naismith, we have players who believe they could play in the top top teams and have a winning mentality.
Winning breeds confidence... We also need some bad performances where we still win. Once we get that physiological winners mentality, we will thrive.
