As I said in the first page of the thread, forget about the Cesc or Cazorla comparison this guy is Iniesta MK2. Watch his U21 U20 or Betis highlights for an idea how ridiculously talented he is. He's not nearly as explosive or physical as Ndombele but as far as getting the ball off one of them you'd 100% back yourself against the Frenchman first.
He's Iniesta not just in playing style but position too. Strictly speaking a CM although a very attacking one, could play on the wing even although he'd be wasted there similar to the Barcelona version. CM is where you want someone with his talent on the ball because he can move the ball forward either running or passing it, even though his final ball is definitely good enough to be able to play him closer to goal too. This with an option to but would be the best deal we've made in quite a while
