Ah, didn't know that about the number 10. A 433 to me is one dm and two cms. Otherwise I use 4231 to indicate the acm. Thats why I picured him on the left in a midfield 3. Sounds like AdM wont be featured a lot in cm then.
And no, I'm no itk. If we are to play with an acm next season his chances of staying increases surely (mata).
Van Gaal calls it a "point forward 4-3-3". It differs from a 4-2-3-1 in that the two CM's aren't considered DM's. It's a very attacking formation.
