It is worrying that Andres Iniesta and Sergio Busquets publicly criticised the strategy Barcelona employed in their 4-0 defeat by PSG but also that another important player in the squad has told his intimate circle "I have not been enjoying football for a while".
It is a comment that makes you think abou the situation that the team are in. It's clear that the tactical demands of Luis Enrique's blackboard don't allow anyone to relax, with each role split between attack and defence. A problem, without doubt, for players who are more used to thinking about the opposition goal than their own.
The frustrating situation transmits itself to the pitch, where Barcelona have gone various weeks playing with fire, in some games they have come out alive without knowng how. For example the league clash at Anoeta or against Atletico Madrid in the Copa del Rey.
Sadly it had to be in Paris on Valentine's Day that everything fell apart.
