Seriously now, I think Wolfe is right in pointing out some of the flaws of the team. Where he is so wrong is attributing those issues to player quality and squad quality, when in fact they are part of different areas. There are flaws in the team which are affecting this team's performances in the CL later stages. That much is clear and realized by pretty much all serious Barca fans around here, that we have issues that need to be sorted out. Hence the panic when we see Rakitic being played even in meaningless games when we know that Rakitic and Busquets aren't at their peak age anymore and if they also tired and exhausted due to overplaying, than a number of teams will probably beat us mostly on intensity alone.
The quality of the Barca team and players however are evident and proven. So, the role of the manager is to find the issues and correct them so that they don't happen again. Instead, he's repeating some of the errors that he did last year, for example overplaying a group of veterans whose minutes should be much more carefully handled. At the same time, he's underplaying the young players.
Most of our issues on the field in CL show a lack of vision and leadership from the manager, and, implicitly, from the board. If it was a lack of player quality and squad quality we wouldn't be as dominant in Spain for so long. We're basically struggling to find a rival domestically who can keep up with us. This is clearly not the sign of a squad who lacks quality players and it's simply absurd to suggest it is.
