Braithwaite opened the scoring when he bundled the ball over the line from close range before Griezmann scored a brilliant volley to double the lead before half-time.
Coutinho added a third with a simple tap-in before Messi rounded off the scoring when he drilled his shot into the top corner.
Full time: Barcelona 4-0 Osasuna.
Messi did this after he scored to remember the late Diego Maradona.

Arrasate will be hoping they can get back to winning ways next time out against Real Betis.
