He won't be patient with kids as Xavi was, that's a given.
Don't think he's that much of an expert either as his coaching career is too short/obscure.
Language barrier will be an issue. Oh, and the club politics. The press will not be lenient on him as they were with Xavi.
Fuck, so much possible negative aspects.
Bojan do your homework:
1) HAs been preparing for 6 months for the job, studying all Barca kids, the ones who have broken already in the 1st team (from Pedri Gavi to Cubarsi), plus the ones that are still in the academy.
Leaks say he is a big fan of most and the potential they can give to the team.
Laporta and Deco gave him many points in the job interview because of that fact alone
2) Coaching career as 1st coach is too short yes. BUT: he was the architect of the German NT from 2008 until the WC win in 2014. The brain behind Joachim Lev. In that sense, he is very experienced
His sextuple win was not a surprise for the knowers in the industry, precisely because they were aware of all that
3) He has been learning Spanish for some months. Dual language assistant is coming to help on that front until his Spanish becomes even better. Besides, language barrier is an obsolete problem nowadays: most players know English anyway
4) CLub politics and press is indeed a mess. Thank God he is German and won't give a flying fuck for all that shit, and what press thinks of him.
First rumors that he wants a sealed locker-room with no leaks from players outside is BIG BIG POSITIVE NEWS
PS: This man got the job because he believes in the team AS IT IS, and that he can turns us into a juggernaut. His past is enough evidence to give him the chance.
Let's not paint everything black. First news and signs are on the contrary very positive
