All tactical systems get sussed eventually and I think we are just entering that period with our's. The opposition now just pack the defence, wait for for our defenders to over commit and play a ball into the masses of space behind. Even with a sweeper keeper as good as Ederson the fact that virtually every side we play has two or three one on one's with the keeper tells it's own story. Arsenal in the FA Cup Semi, Lyon, Chelsea away, Leicester at home. All losses against decent sides packing the defence. We need innovation, should be interesting.
