The champions have found it more hard than usual to break down opposing defences this season, with the lack of goalscoring form of all their top dogs, including Cristiano Ronaldo and Karim Bemzema, raising eyebrows.
The Champions League has been a different story, though, as Ronaldo once again leads all scorers with eight in five games. It may not be the best start to a season ever, but we're still there and we will fight for every title.
And it's not just their league form that's been patchy.

"But when it does, it won't stop, so we have to keep working".
Sergio Ramos has sought to rubbish reports suggesting that there is a rift between him and RealMadrid team-mate Cristiano Ronaldo.
