La Liga on Sunday released a statement saying Lionel Messi’s Barcelona contract was still valid, days after his shock announcement that he wants to leave the club and hours after he failed to attend a pre-season medical.

Messi’s failure to show for his medical underlined the 33-year-old’s determination to leave the club he has been with throughout his career.

The six-times world player of the year insists he has a clause in his contract that allows him to leave on a free transfer — a claim disputed by Barcelona and now by La Liga.

The ruling body said the only way a club can sign the Argentine forward is if he triggers a release clause of 700-million euros.

“In compliance with the applicable rule, La Liga will not approve a request to be de-registered as a player with the Spanish football federation, unless the amount in the release clause has been paid,” La Liga said.
