I still think all these calls for his sacking are extremely premature not to mention nearsighted. Sack him and what? Go with an assistant coach for the remainder of the season? How's that going to help? Then do another coaching search next season, with a transfer bad in place, with this board still in power?
Lucho needs to be given time to work through the issues. We cannot have this reactionary impulsive drive to fire a coach every time things are not going perfectly.
In a way, I see what he is trying to accomplish. He doesn't have a prime Xavi and Iniesta to focus around, but he does have the most talented forward line in the world. A forward line who quite possibly has scoring and creativity in equal measures. So he is transitioning the team from a midfield centric team to a forward centric team.
The problem is he has set up the team so much around the forwards, that he has totally disrupted the midfield and effectively broken the team in half. He is yet to find the balance in which he still gets a forward centric team, but still has a supporting and structured midfield.
Quite frankly, I think the team needs to move towards a more defensive structure. I know this is not what Barca fans want to hear, with the pedigree and mandate to play total football and all, but I just don't think they have the midfield players anymore to dominate playing like this. The talent gap in that midfield from 4-5 years ago to right now is pretty significant.
With a creative and self-sustaining forward line like the team has right now, a more defensive and supporting structure I think will work best; and no, I don't mean midfielders defending wings. I mean fullbacks defending wings, and midfielders defending the midfield. Less creative and controlling midfield, true, but more structure, harder to break down, more recuperating, and allowing the forwards to create for themselves with freedom.
IMO this is how the team needs to look in attack:
and like this while defending:
