I don't know why people think 30 million for Lloris would be overpriced. For a world class player who can play at the top level throughout 5 year contract, already knows the language and is settled in the league, this is peanuts money.
He is also open to a move, and most certainly would hand in a request to get it. The reason there is no talk of GKS is that De Gea hasn't left, and the club arent interested in money. Decent chance he goes on a free next season.
