Well unfortunately I think anyone who knows anything about football in a tactical sense, learned from the game yesterday that Southgate is lacking. He's great at man management, motivating and media handling etc.
But tactically it was all wrong, especially in second half we needed to change and stem that tide. Their fullbacks had so much space, the system needed to be changed. He only made subs that had no impact, like for like players. It didn't impact the game at all tactically which it needed.
I thought Steve Holland was more in charge of the system in that regard, but they both didn't spot it seemingly as no changes were made. Everyone else saw it so why didn't they change the system.
