Lionel Messi hit a sumptuous hat-trick, to help Barcelona clinch their 25th league title and their seventh in the last 10 years, relegating Deportivo La Coruna in the process.
When Philippe Coutinho opened the scoring after just seven minutes, and Messi doubled the lead 13 minutes later, the party started at Catatonia
But Lucas Perez pulled one back for the Galicians before half time to halt the celebrations.
And Emre Colak pulled Depor level in the second half, firing home after Celso Borges set him up to set up a nervy finale.
However, Messi had the last say as his two goals in the dying moments clinched the title for Barca as the Catalans ran out 4-2 winners and send Seedorf’s men crashing.
