A bit too many conspiracy theories here. I mean I agree we're not in a great place at the moment, but to question our players' professionalism and Tata's abilities this way is overreacting.
We have to get it in our head that we were bound to decline after 2008-2011. Now that's certainly not a reason to welcome any problem we face in a fatalist way, but we should also look to other teams and a more distant past than Pep's era when we judge this team.
Top teams in la liga are winning a lot more points these recent years. If we faced this RM and especially Simeone's Atletico under Pep, well I'm sure we'd still be more confident than now, but we would never have felt so comfortable as when competition was softer.
My point is this team's standard of performance was bound to decline but is still very high. Even when currently "off form" we are easily in the best 10 teams of the moment in Europe. When we are on form we are one of the best two, or three. Compared to Pep, yea that's a decline. Is it impossible to win titles with such a team ? Hell no.
And, this is a transition season. The big moves will happen this summer. If they don't then I for one will be seriously worried. Remember Tata can't say anything he wants to the press, and he hasn't had his chance to make any signings. I think he is doing all right considering the cards he was dealt. He is not perfect but calling or even wishing for him to go is premature and unfair in my opinion
