I think what the game showed is we have a real problem with squad depth. we were poor against a league 2 level team until we brought on the big guns.
I think it shows something a lot deeper TBH. Other teams like Brentford and Brighton have seriously average players but they play well in a good system.
Our football is basic, it relies on Individual players pulling rabbits out of the hat, that why when Son or Kane don’t play we look poor. The movement of the team in attacking phases is more on the manager than players. We are a very poorly coached team and have been for a while now that’s why we are reliant on the brilliance of our elite players almost totally.
