Last year, teams wouldn't press our back 3 (bar City, Spurs, and Arsenal in the FA Cup Final) That in itself gave us the advantage as we had the space to move the ball freely and as a cohesive unit. Mix that in with no European fixtures, the focus and fitness of our players were top notch.
We are easily exposable now. Teams now know that if they put pressure to our back three, it forces our wingbacks to drop deeper. They put pressure on our wingbacks, especially limited ones like Alonso and Moses, we only have two midfielders as outlets, to which they themselves are under pressure, leaving us no choice but to hoof it. I believe this has created a lack of confidence in the side. Change is needed and a good run of victories. I'm 100% sure Conte is capable of it.
