I think I have just started to realise whats going on with neymar, first of all look at his shooting this season, at the UCL he averages 1 shot per game! as a second striker/winger while messi for example averaging almost 5.
At the first year he was pretty good, at the second he was great and was on a perfect role, a killer finisher to messi's crazy passes and another danger on the opponent's goal.
Last year he improved his passing drastically, and was the best when messi was out, but the moment when messi got back on track and gained some fitness, he disappeared again,
But overall he was great last season and had a huge improvement despite scoring less.
And now we got this season, wonderful passes, killer dribbles, just like last season but with a "tiny" difference, to make the wrong choices and to not take any shot on goals! no more excuses, its his fourth season as player,
And he is very important to the team, but its like his brain got backward to the first season, and after 4 years we can sum things up by saying he is still at the comfort zone and didn't developed as we expected (although the season isn't over).
I think that he is comfortable and want to the be the no' 2, the only reason he stepped up last season is because messi was injured for a much longer time, not a game or 2 so he didn't have a choice,
He prefers to keep on and passing to messi and suarez hope they will score and do the hard job, it doesn't seems like he want to develop as a player, and at almost 25 he think he still got to learn from messi and keep relying on him like a coward.
If he was an average player like pedro for example i wouldn't go mad, but he is the most talented and complete player at the past years besides messi and he doesn't get advantage of it, there some situations while he really needs to step up,
Even when messi is on field, but he is so predictable, he is run through the defender and automatically look for a pass even if he needs to shot, unfortunately his personality won't let him to discover his full potential, not to mention those silly fights
Every game, he makes wrong decisions too much and do the things same again and again, but he is so freaking talented that almost every game he has an assist or he does a thing that gets us closer to win.
But after I realised it I think I don't have more high expectations from this guy, maybe he will surprise us all somehow.
