I agree. I think neither is to blame the way we play. In the 4-2-3-1, for your main passenger to consistently be the 10, you have no chance really.
Take tonight, when Fred & McTominay get the ball, you can see they want to be positive with their passing, always looking forward, but there's literally nothing ahead of them. Mata is awol struggling to keep up with the pace of the match, providing zero support. Other matches it's either Lingard or Pereira either not intelligent enough/not enough quality/both.
Only option i can see is, we need to change this god-awful system which clearly isn't working until Pogba gets back.
