Dyche obviously as the new owners wanted their own man. Zola lost confidence and jacked in his 2nd season. Saninho was the quick fix but also a fruitcake who couldn't take it anymore so wasn't offered a new contract. Jokanovich got us up but wanted too much of a bump in wages so wasn't kept on. McKinley as mentioned was never a manager. Garcia had heart problems and his replacement Flores got us safe but then basically stopped working, his contract wasn't renewed. And then Mazzari was sacked for the crap he produced last season, it was driving fans away.So "head coaches" haven't been sacked...rather decided they no longer wanted to remain at Watford? Is that better lad?
Now here we are with a coach we very much want to keep hold of.
