He has saved us a brickload of money.
Hope we don’t make his supreme ability / versatility cost him a no1 position. I Already prefer him to Sanchez and Aurier.
Why didn’t Poch play him more??
I think he's going to be at FB for a little while, and then move into the center. I'd give him a season being our first-choice RB, and then move him into the center as our first-choice CB the season after next.
His defending style is amazing - it's aggressive, it's on the front foot, he goes into players at just the right moment when they've started to lose control of the ball while dribbling. But that same style is why he might get caught out of position at center-back in a two man defense, which is what Mourinho seems to prefer.
He'd be a perfect sweeper in a three-man back-line, but for now, to learn his trade and get to grips with when to commit and when to stand off, I think he should spend a bit of time at right-back. with him on one flank and Davies on the other, we can go back to a very traditional style of having full-backs be part of the defense, and leave Lucas/Bergwijn and Son to provide the width. Would make us more solid, and also more of a counter-attacking outfit.
First things first, though, he needs to sign a new deal. Bit worried about that, and hopefully it's sorted soon.
As for why Poch didn't play him, we don't know what the reasons are. Maybe he's only just become good enough to start, maybe Mou's style suits him more than Poch's style did, maybe Poch was just protecting him from undue expectations. No sense judging now.
