Italian giants Inter Milan are holding out for £12m for their highly-rated midfielder Cesare Casadei.
Casadei, 19, is yet to make his senior professional debut but is seen as one of the great emerging hopes out of Italian football at present.
Such is his potential, Chelsea have been chasing the player all summer and have seen a bid of £6m turned down by Inter for the player.
Chelsea have extensively scouted the box-to-box player who it is said will initially be brought in as an academy signing with a view to eventually bedding him into the first team.
