We'd have either had to play Neves or Moutinho semi regularly to accommodate, even then we're assuming vitinha could play in a 2.
Or we play a 3 in midfield which is something we've done once, I think, this season.
Don't get me wrong, I rate vitinha and think he will be excellent. But if we're being frugal and it was a choice between RAN and Vitinha then I think we made the right choice.
We'd have seen less of Moutinho already if Lage rated Dendoncker, however it's quite clear he doesn't.
