Not gonna lie, never heard of him. He is seriously good, or a "talented" lad who has not actually delivered?
He started for Brazil in the 2014 World Cup semi final (the one they lost 7-1!)
Was seen as a huge talent at 21 but was sold to Shakthar for £22m. Done well there, particularly in last season but it is Ukraine so nobody noticed. Scored a brilliant goal against City in the CL.
