I probably should've used a different term than flexible. Pep tries a lot, the formation is very fluent, with players changing positions or even the team changing formation (during match), I'm just worried that while all that might be a great idea in theory, it could be too much in practice. The focus still seems to lie on ball possession and slowly putting pressure on the opponent (similar to tiki taka), but I fear that alone is too predictable (i.e. not flexible enough). Then again, now is the best time to experiment, so I don't really mind for now.
As for Bla, I'm guessing the last picture did him in. Given that I complained about it (though only in the thread) I feel a bit responsible for that.
