That was my point - Rafa doesn't tolerate players not doing exactly what he wants them to do. There's no wiggle room with regards to "he thought the short pass was a good option there". And the fact is that Rafa blames Mbemba for the midfield giving the ball away in that game, because even though his passes went to feet, they went to players who then turned it over and, in Rafa's plan, they should never have had it in the first place.
This was reported a few weeks ago, pretty sure in The Chronicle. It fits with what we know about Rafa, it fits with what we saw in that game. Rafa had a plan, Mbemba didn't follow it, we lost, Mbemba doesn't play again.
There's just no way in hell a manager that successful sees the game like that. It's a game of decisions based on the model you've been taught. Based being the key word. Fair enough if you ignore the plan for large periods of the game and don't make the pass when its there but to say there's no wiggle room is crazy.
Don't ex-players all say similar as well - it's a very strict and disciplined approach from rafa and he's not afraid to drop someone who takes liberties. Saying there's absolutely no wiggle room though is probably a bit far but there's no question the margins are very fine with what he'll tolerate.
