Barca haven't really looked up for it mentally this season. There have been losses in La Liga that will ultimately cost them the title and then then losing away 3-0 twice in the CL... you can't expect to keep on doing that.
They've spent really poorly last summer and they're overly reliant on the front three, which as good as they are isn't sustainable.
Monaco is the dark horse but I'd be tempted to say Real again.
Not sure if I should start a new thread on this, but I was thinking of how would 'we' fix Barcelona considering how poorly they've bought overall in the last few years. They just waste money on such unnecessary tools (Gomes, Turan, Digne, Alcacer etc etc).
They need to replace Dani Alves - that has killed them this year. They were never going to find someone who works that well with Messi but they fucked up royally but not replacing him.
They need a top CB - Pique is decent, as is Umtiti, but neither are world class defenders. Aldeirweld should be someone for them -
THey need to replace Iniesta. He's still good but he's clearly not nearly as dominant as he once was, and that leaves their midfield run over more often than not ... Another midfielder in the Rakitic mold to help out would be great for them too ...
