Oh please, everyone has to start somewhere. It's quite obvious he's more talented than having to play for Leicester the rest of his career. There's NO WAY he'll spend the remaining three years of his contract in that town - it's out of the question. A player has proven his quality and should be playing at a level where he belongs (Man United, Chelsea, Bayern, Madrid, Barca). That's why there are big and small clubs.
You people make me sick. No wonder the market goes nuts this time of year. No gentlemen agreement at all. Using the logic of the quoted poster above (hobbers) you shouldn't be able to sell him for that price because you bought him for like 300k a couple of years ago.
I'll give you a really honest price on your player. £50m fair and square. Just look back at some of the deals within this region of money (Mata, Di Maria, Torres, David Luiz, Özil). Saying no to that sort of money with all that info in mind could really piss the player off.
