Barcelona began the post-Lionel Messi era with a 3-0 win over Juventus in the Joan Gamper Trophy on Sunday - summer signing Memphis Depay opening the scoring and setting up the second goal for Martin Braithwaite.<br /><br />Depay broke the deadlock in only the third minute after being played through by Yusuf Demir and the Dutchman's 57th corner kick was headed in by Braithwaite.<br /><br />Substitute Riqui Puig then sealed the win in stoppage time with a shot from the edge of the penalty area that Messi himself would be proud of as Barca won the traditional pre-season match for a ninth season in succession.
