The surprise to me is why our full backs struggle so much with the wing back role. On paper, our formation should have worked really well against how they set up. Sure we know the midfield lacks creativity and King, Fraser and Wilson had poor games - but that would still have been the case regardless of formation.
You’d think with us having attacking FB’s they would take to playing at WB with ease. It’s been proven anything but that. I can remember ages ago Warren Cummings saying he preferred FB as he could get further forward! At WB you are responsible for the entire flank and play too passive both going forward and defensively.
Interestingly the best success we’ve had with the 3-4-3 has been in victories over Arsenal and Chelsea. On both occasions we played Wee Man at wing back. Perhaps then, if you want the WB role to work, you are better off playing natural wingers rather than confused full backs.
