What is wrong with our current formation?
Only concern for me is there is no proper replacement for the role Rakitic plays in the game for us. None of the current midfielders we have fit the bill. I thought Arda could do the job but he is too slow and doesn't show the energy needed for that role. Plus his positioning is all wrong.
Spain vs Italy showed us the dangers of dogmatically sticking to a 4-3-3 regardless of whom we play. I just want us be able to play more than one formation effectively. It's precisely what Germany and Löw's team does so well, finding tactical answers to the team's we face. This would be really good against really defensive teams and in particular, Pathetico.
Also, I'm skeptical of Vidal's ability in both sides of the field. To be fair, he didn't play enough last season for us to get a consistent look at him in that role and from what I saw, I liked what he had to offer in the offensive final third but in the defensive final third, I wasn't convinced. He's not the greatest positionally in that aspect and he's not as strong of a tackler as Dani was.
You guys will see how invaluable he was to that aggressive 4-3-3 there when it doesn't look right this season. Dani was a much better defender than people gave him credit for, really good at making strong, clean tackles on the fly and while he definitely had dips in form, he really showed his class his last two seasons here. He really stepped up under Lucho and him and Pique had a renaissance under Unzué's defensive work with the team.
So rather than be in an already on paper half-broken system next season, this sort of formation would be intriguing for defensive teams to deal with and it puts less defensive pressure on the wing backs to allow them to play higher up the pitch with less risk.
Honestly though, perhaps a return to Guardiola's first 4-3-3 wouldn't be bad with Umtiti in the squad now. Something like this:
[formation=barca,6]
ter Stegen
0-0-Piqué-0-Mascherano-0-0
0-0-0-0-0-0-Umtiti
Vidal-0-0-Busi-0-0-0
0-0-Raki/Rafinha-0-Iniesta/Denis Suarez-0-0
Messi-0-0-0-0-0-Neymar
0-0-0-Luis Suarez-0-0-0
0-0-0-0-0-0-0

The idea of Vidal and Alba both bombing forward in our current setup just seems to risky now to me. It's either a tactical change or we sign a proper RB like Fabinho or Cancelo. Sorry, but Roberto should not be reasonably considered long term at RB.
