It's not right to consider his 42 months with us, and only judge him on the last three. He took us from a relegation place in League 1 to 4th in the Championship, breaking records on the way.
Yes, it ended in tears, but so do most managerial appointments.
The playoffs are a lottery. Watford were, by far, the best team out of the four, but failed.

You won't find any manager totally committed to one club, ever. Some keep quiet about their ambitions, others are honest. Football is a dog eat dog industry & realistically, the only loyal ones are the fans.
