Stats are very useful when you have a large dataset (like a football season) and it is hard to remember everything qualitatively. Stats are not an argument themselves. They can just be used as evidence to support an argument. I'm not judging my entire opinion on the two seasons based on whoscored stats. I'm using them to provide evidence to my own opinion which I've already talked about.
On the pitch, I can see every week that not only is the team looking lost more often but it's also increasingly looking towards only two players to solve that problem. The decisive actions are becoming more concentrated (sure that approach has its own merit when you have a player like Messi who is probably one of the most consistent ever) but putting all your eggs in one basket is still a risky approach nonetheless. What's more important is that the best teams are getting better at figuring Messi out, however great he is, and the team doesn't have any solutions to cope with that issue.
This season there are 4 barcelona players ranked between 27-30, With a rating between 7.17-7.19
Actually I did know about that. I just didn't talk about it for a couple of reasons:
(1) 2 of the players don't have as many games played as others. Look at Tello and Adriano with only 10 starts and 15 starts respectively. Less datapoints = not as strong data.
(2) Compare the absolute difference in ratings of 2012/13 from 2010/11 :

The 7th best Barca player in 2010/11 has a much higher absolute rating than the 4th best Barca player from this season. Just also check how Messi is the only player who managed to maintain his absolute rating. Most importantly compare within our own players and how the gap in ratings is increasing.
(3) In 2010/11, all 7 players played different positions and all were first team starters. That means, on average, a big part of our first team (i.e players on the pitch) consistently played very well throughout the season.
While in 2012/13, Xavi, Iniesta, Fab rotate each other - Adriano and Tello are not regulars either. That means, on average, we have less of those high-rated players on the pitch at any given time.
I did not want to go into a long discussion about my reasoning that's why I kept it to myself.
