MADRID - Barcelona fans have many more years to enjoy Lionel Messi, assured outgoing coach Luis Enrique after the Argentine handed his boss a successful send-off in a 3-1 Copa del Rey final win over Alaves.

Messi opened the scoring and helped set up goals from Neymar and Paco Alcacer just before halftime as Alaves slumped to defeat in their first Spanish Cup final despite Theo Hernandez's stunning freekick equalizer.

"He is extraordinary, an extraterrestrial," Enrique said of Messi after he lifted his 30th trophy at Barca a month ahead of his 30th birthday.
