This isn't baseball where stats are king, you have to observe the players & the play...If you look at Messi and his performances over the past couple of weeks, there's no way anyone can legitimately claim he's 100%...Whether that's down to fitness or any other factor, no one knows but it's clear something is off.
Some of us have already said similar over Iniesta and even Xavi whose influence in matches have been palpably absent...Perhaps it is indeed Tata
If you haven't already seen where Neymar's future position in this squad is (Leo's spot) then you clearly haven't been paying attention and being unsettled doesn't equate to having a personal beef with a player, it can be a variety of other indirect factors...Media focus at the club has typically been focused on Leo but with Neymar emerging as a star at the club, the spotlight has shifted to the Brasilian and his Nike PR machine...It is merely a possibility, one that others with more understanding of the club, the players & football have alluded to before he even arrived...Nothing to do with Neymar possibly being an Ibra, that's an unimaginative conclusion/comparison to make.
Learn to read body language, Leo's will reveal something not being quite right...And as I already pointed out, Sport isn't as reliable as MD when it comes to club matters at present but they rarely dish on key players, nevermind Messi...We've already read previously that Xavi had a talk with Tata due to concerns over tactics so perhaps the reported meeting was more about this than Leo himself...However, something appears to be going on behind the scenes
