Okay, so 'meltdown' might be a little strong for last season's treble-winners and the best player on the planet, but the few weeks they have endured suggests there may well be something to worry about.
They will hope that Champions League elimination at the hands of Atletico Madrid after taking a first leg lead to the Calderon will be the nadir of their season; but their form of late, which has seen their league lead cut to just three points, hints that further trouble could be afoot.
Lionel Messi is suffering one of the worst goal droughts of his glittering career. The presence of Neymar and Luis Suarez was supposed to have taken pressure away from the Argentine to the extent that it didn't matter when he was not firing. He is off form now, though, and the team is struggling terribly.
He has failed to score in five consecutive matches, last scoring against Arsenal a month ago, meaning he has gone 452 minutes without scoring a single goal. That is his worst run since May 2011, and he will surpass that drought if he fails to net inside 23 minutes against Valencia at the weekend - something that looks a distinct possibility on recent evidence.
With 22 goals and 10 assists in 27 La Liga appearances so far this season, we can legitimately call this recent run little more than a blip for Messi, but Barcelona need him to rediscover form before long or their season could fall apart.
