Leo's combination of lazy/ineffective today is a clear indicator of how off form and maybe fatigued he is at the moment IMO. Let's not forget he pretty much plays every game and never had ridiculous levels of stamina in the first place, let alone now when he's reaching 30. He did used to have issues that were at least partially due to a lack of energy back in 13/14. I'd have to imagine that the level of quality rest/preparation he or the other players could've gotten post-PSG and before this game was under par too. He was really shitty today, didn't lead the team as we've come to expect.
There's a full week before the next match now, hopefully he and the coaching staff take the proper measures for him to come back sharper and in form next time. In the months where we can't afford much less than perfection, we need Messi to be at a very good level. I feel like people have forgotten that even at his best his form did fluctuate at times during the season, this is clearly a dip. Can't let it continue for much longer tho.
. If not, then that's just a matter of opinion and an argument on a far bigger scope than anything this match had to do with.
