Doesn't look like Araujo will make it. So it will be Mingueza-Lenglet-Umtiti. A clean sheet seems delusional and there is no need to rush Araujo back as there are much better chances of winning Copa or maybe even La Liga.
The new system offers more protection for the backline and Busi's lack of pace isn't exposed as much, but it is just not realistic to turn this around. I'd be happy with a decent result given the circumstances. Test the new system on the highest level and see what we can get from it.
If someone said in October that Barca will be out of CL, but has chances to win Copa and is fighting for La Liga in March, I'd sign for that. I mean, how many points was Barca already behind Atletico? Putting things into perspective, thinking about all the shit the club was going through at the end of last year, economically, on an institutional level, the situation today looks pretty decent.
