I don't know if it is just my very specific play style, but i don't get it why this card is so cheap.
I play him as an CM in 433, but with instructions to stay back (what he actually does, not like Kante for example) and block the mid.
And for me personally he is the best card that I've used in this particular position/role. I had Kante (93 MOTM), his passing was too terrible for me and he never stayed back whatever I did in the tactics. I had Henderson who just didn't feel well in defense, probably better as a box to box CM. I'm not gonna talk about the various gold cards I've played...
So:
-> I always feel safe because I know he is in the back
