I think he is already making waves if comments in the media are anything to go by.
Regardless of how or if he joins Leicester if he turns out to be brilliant then he will be off regardless, so I'd rather we got 4 years out of him and then sold him on for a massive profit.
Unless you are Barcelona, Real Madrid, PSG then this is the reality of football, Even Chelsea, Liverpool and Man U lose players to other clubs, we are a stepping stone but we are higher up the ladder compared to a few years ago.
