I blame players before manager.. at the end of the day tactics or not, its only the players out there on the pitch, with there ability and whatever attitude they have at the time. Getting on your managers back only makes things worse!!, you show me a club that has critisized its manager and then everything has come good shortly after??
It doesn't happen, if he feels tho we want him out, he will panic and choose to play even more defensive/negative football because he will be TERRIFIED of losing. Its not the way to go, if you want to blame anyone blame the players!!.
