So what did they expect? Loyalty? He was passing through. Everybody is, at Watford. The manager, the players. Hell, English football had to change its rules to guard against the transitory nature of the Pozzo family's vision.
Remember plan A: 14 loan signings, 10 from Udinese in season 2012-13? The Pozzo blueprint ran so against the spirit of the game that, after one campaign, both the Premier League and Football League wrote new rules to prevent it happening again.
The conveyor belt of disposable managers, however, is beyond their remit. Watford have dumped or lost nine now, since dismissing Sean Dyche in July 2012.
