Messi hat-trick clinches title for Barca and relegates Depor
Lionel Messi put the icing on the cake as Barcelona clinched the La Liga title with a 4-2 victory over Deportivo La Coruna, who were relegated.
Barca did not have things all their own way against a spirited Depor, who fought back to level through Lucas Perez and Emre Colak after Philippe Coutinho and Messi had put Barca 2-0 up.
Depor were forced to push forward knowing only victory would be enough to keep their survival hopes alive and they paid the price as Messi added two late goals to complete the 46th hat-trick of his career.
