Wolves manager Julen Lopetegui says Manchester United are currently one of the best sides in world football ahead of their Premier League meeting this weekend.
United have won both of their matches following the World Cup in comfortable fashion without conceding a goal, but they face what looks like a tougher test when they travel to Molineux on Saturday.
Lopetegui led Wolves to an impressive comeback win at Everton in his first game in charge and will be hoping to carry the new manager bounce into their meeting with United.
