Forget about the formations forget about whether we need him or not right now. Now we have the chance to sign a 20 year old Brazil national team regular starter, future No.10, at the price of merely 20M pounds in current inflated market, we would be just stupid not to, let alone he is versatile enough to play in the double pivot and right midfield/wing. I would like to make a bet that if he stays at Internacional this year, his price will be sky high in the near future and all the top clubs will love to secure his services. Just my 2 cents.
