I swear some people forget the shit Tito took, Tata took or likes of Xavi took when claimed Barca were better team away to Bayern as had more of the ball.
This idea that the way the team plays is most important thing goes out the window quickly when try to play that way and lose.
Barca are playing well and it is not a strict 4-4-2 anyway other than when defending.
Repeating the same thing over and over doesn't make it right. In the other thread you said Barca haven't played 4-4-2 nor a 4-3-3 all season... You seem to be of the opinion that formations and tactics are static and that shape must be maintained at all times. Every football publication as well as fans can see we're playing a 4-4-2 system but JamDav says otherwise and is willing to go to war with the custodians of football analytics, Opta, to prove his point. But before you do that and make a fool of yourself lets try this one more time.
Any system can morph into pretty much anything when in possession of the ball. A 4-4-2 can become a 4-3-3, 4-2-4, 2-4-4, 3-3-4, 3-5-2 etc etc and when not in possession it can morph into a 4-5-1 (which seems to be the case with Barcelona when Suarez helps out in defence), 5-4-1 etc etc but the fundamentals are still that of a 4-4-2 system, 4 defenders, 4 midfielders and 2 attackers.
The 4-3-3 (False 9) system we employed earlier in the season morphed into a 3-4-3/3-4-1-2 with Messi dropping deep and the full backs linking up in midfield and further up the pitch.
Don't take my word for it...
This is on the official Barcelona website using the Opta stats you're so keen on debunking.
When not in possession this 4-3-3 system morphed into the 4-4-2 you describe but it can become pretty much anything like a 4-4-1-1 or 4-5-1 with the attacking wide players joining the midfield but again the fundamentals are that of a 4-3-3 system, 4 defenders, 3 midfielders and 3 attackers.
So for the sake of consistency, I'm going to show you the players average position since the Girona game when the 4-4-2 system was implemented.
vs Girona
Vs Sporting
Vs Atleti (Bear in mind there was a tactical change in this game around the 60 minute mark and Gomes was shifted from a RM to LCM role so he's average position will be skewed)
Vs Atleti (After tactical change - Clear 4-3-3/3-4-3)
Vs Malaga
Vs Bilbao.
Edit: Clear flat 4-4-2 as you can see which at times morphs into a 3-5-2 when in possession.
