I have never seen a single second of Tomiyasu playing, but what today demonstrated is that if we intended to play five at the back, we need a specialist wingback that knows how to play the position.
I really like Tanganga but he’s not that player. He’s a RB in a 4. I hope Tomiyasu isn’t a ‘bits and pieces’ RB. We need specialists and a fixed formation that we’re confident with.
