Wigan Athletic boss Roberto Martinez believes that Manchester United are "better" than Champions League holders Barcelona.
The Red Devils lost to the Spanish giants in the Champions League final last season, but Martinez is adamant that United's "mentality" is the best in the world.
"In many ways they [Manchester United] are better than Barcelona - that's just down to the mentality, the belief and the way they approach games," Martinez told talkSPORT.
"What Barca have is the way they play the game, they are very unique. But United have a blend and mentality in the squad that is the best in world football.
"It's just a matter of beating a team like Barca in a one-off game and see who can be European champions, as I believe they are on a different level than anyone else."
The Premier League champions have a 100% record so far this season with five straight wins.
