Lionel Messi has shocked Barcelona chiefs over his new contract demands. Barca are keen to extended and upgrade Messi's current deal, which runs to 2016, before Christmas.

The Argentine has been tentatively offered a contract worth €10 million-a-year, but the player's camp has stunned Barca with demands of €15 million-a-year, says El Economista.

For the moment, Barca are yet to respond to Messi's request.
