Why do i have a feeling in my kidneys that a lot of teams in the PL are going to switch to 3 at the back because its trendy or they think it's a magic bullet?
It's already happened for a lot of sides. Every few years a formation gets rehashed as being the next big thing. Remember when two strikers was standard? Then suddenly it's all about one up top etc
I long for a return to the 5/6 forwards that was apparently all the rage back in the 50's!
