As I said, by Madrid's standards they were poorer than previous seasons.
A lot of results I've given there last night highlight numerous games were they under performed. Yes they are of course
still one of Europes best attacking teams, one of Europes better teams no doubt. But again, things weren't great. Again to give you the example of Di Maria, didn't he under perform in an under performing United side last season?
Looking at Whoscored.com again I know it's only stats but Bale was Madrid's 3rd highest Rated player with 7.66 rating for the overall season. Only Ronaldo and James bettered him!

Bale was their 3rd highest top scorer with 13 goals and 4th in assists. Again he was in the mix for both goals and assists and heck his performances were rated highly enough also.
His performances dropped off but still he delivered. Your buying into the fans negative reaction of him far too much.
Oh and the obvious answer to your question if not Real then who, is Barcelona. Other great attacking teams from last season, Munich of course, Wolfsburg and Arsenal.
