Lionel Messi has signed a two-year contract extension with Barcelona, linking him to the Spanish club until June 2018.

The 25-year-old Argentina forward joined Barcelona when he was 13, and debuted with the first team three years later. He has gone on to become Barcelona's all-time leading scorer en route to winning four FIFA world player of the year awards.

Barcelona first announced in December that Messi, along with midfielder Xavi Hernandez and defender Carles Puyol, had agreed to extend their contracts.

Barcelona defender Jordi Alba says Messi's renewal "is great news for Barcelona."
