You do realise that if we had a top CB next to maguire we wouldnt need a mcfred double pivot to shield the defence? Agree a top DM would be nice but CB is more important. Championships are built on defences.
I get what you and another poster are saying, and I agree to an extent as it's why I was insistent on Bailly playing more as for all of his faults he allowed us to be much more aggressive in gaining territory higher up the pitch.
But overall when I watch us go against any top side, the glaring issue is a lack of a midfielder besides Pogba that teams are afraid of. City/Liverpool/Chelsea/PSG etc all do the same thing in aggressively pressing McT/Fred/AWB because all of those players are awful on the ball under pressure and it leads to losing possession and control of the game. Which is why we tend to sit deeper in those games and willingly have them try to punt balls over the top: A safe option that has a low likelihood of success but also won't lead to easy chances for the other side. I'm of the opinion that a top DM that is able to play through the lines with confidence would allow us to punish teams that are gung ho without relying on Pogba to be the only one that has the quality/technique to play those passes.
In the end both positions are vital for us to upgrade the squad, so here's to hoping they both are addressed this summer.
