Rumours are swirling that Lionel Messi is unhappy at Barcelona, but prising him away from the Catalan club won’t come cheap.

Chelsea and Manchester City are both being linked with a move for the Argentinian, but the Sun are reporting that it will cost them a staggering £500m to sign him. That figure takes into account a transfer fee of £200m to Barcelona (activating a reported buy-out clause), and Messi himself wanting around £300m in wages and bonus.

Chelsea are apparently willing to offer him a six-year deal.

Earlier this week, a study said that Messi was worth £173m. Seems like they undervalued him.
