There is literally only two ways this will go.
He is either someone Roberto has been watching for a while, who he thought was ready to make a real step up, and after his banner year Everton have seen enough to go right, fucking get him in now because he's about to explode onto the scene.
He becomes an instant cult hero with his mix of high tempo, Jamie-Vardy like closing down of defenders and chasing lost balls, and his better-than-kone like ability to make an take goal scoring opportunities, ending the season with ten league goals and 8 assists, propelling us to 6th and an unlucky quarter final fa cup run loss to Arsenal.
Or he's going to be absolutely, painfully, shite. He's going to look like a competition winner and it's going to be obvious we were had for bad, bad mugs.
He's had one good year, and most of the goals bounced in off his arse or slipped under the keeper, so much so that they called him the lucky one?
Personally I think the first.
