I'm positive he will become one of the best CMFs in the world if he isn't already.
I wish I could find footage of his games to play them at 50% speed because I'm pretty sure we could see a lot of interesting moves from him off the ball. I'm saying that because his intelligence and anticipation are absolutely insane, he already knows the the right thing to do before he even has the ball and he's always one step ahead of his opponents. On that goal vs. Juve where he assists Vidal? I think with a cross from the left wing, he's basically outsmarting Frabotta hard (which isn't saying much in hindsight because wtf is Frabotta doing, defensively speaking?) but even when it doesn't seem to pay off, he's smart enough to hold the position and keep this advantage even though the play seems to go against it, and it pays off.
His performances seem to be full of smart plays like that.
On a more game-y aspect, I like the pace in his ground passes (higher sps?) and his TW seems insane, oranges for sure, reds might be pushing it. It's a tricky one because the sheer quality of his support is very high. The amount, not so much, actually way below what his energy levels imply.
His technique also deserves a shootout, very clean traps all around. Also, heel passes are clearly his signature move and he needs the card.
Everyone knew it was impossible. Then came along a fool who didn't know it, and he did it.
