Milwall didn't sack him, he went to Ireland. The others sacked him because he WAS taking them down.
he left millwall 14 points clear of relegation - they were relegated
he was sacked by sunderland with 10 games to go - they were relegated
he was sacked by wolves with 13 games to go and out of the bottom 3 - they were relegated
it may be your opinion that they were going down but it's not the fact.
