It's more of the same really, March-May and now the first two months of the new season, 5 months of football (or thereabouts), it's just not good enough, for the investment and the length of time he's been at the club, at the very least a new manager would provide a boost to the club, he's going to be sacked eventually, why wait til the situation worsens?
I'm not one to call for change willy nilly, but this is an irretrievable situation imho, the standard of football is shocking, and tactically he's just guessing at this stage, 4 goals in 6 league games is fucking abysmal.
