20 games in a row is quite excessive. But, for example, if your squad comes down with a flu bug and you end up with half the squad out injured or suspended. Do you blame the manager now he's had to resort to playing the U18's? Sometimes the manager can do everything and you end up just waiting for your better players to come back.
For me, this run of bad form we had was down to a few things. The fixture congestion over Christmas and the tiredness, the injuries and suspensions and the lack of a quality forward.
It's not like Bilic was setting us up entirely wrong, and for the most part people agreed with the majority of the players picked. He tried bringing Hegazi back in, and that didn't work so he took him back out. We've had to persist with Townsend and O'Shea, who wouldn't be my first choice. Biggest criticism you could aim is probably that we stuck with SJ in goal, but he's not been that awful lately. What other line ups should have tried that would have fixed any perceived problems?
It's not that he shouldn't be criticised at all, but that there were clear circumstances which were obviously going to affect the performance of the team.
