"He is young and enthusiastic, just a great manager to work for," said King. "Obviously when jobs come up he's going to be there or thereabouts but he's got a job here, he's under contract and all the boys love playing for him. His main focus is Watford.
"Aidy Boothroyd, the team and the supporters have come a long way in two and a bit seasons, and now there is unfinished business. This season has got to be finished.
"We've got one aim and that is to get promoted, and I think we are on target to do that.
"I don't think the manager would be tempted to walk away. He's gone out and spent money, he's brought in the likes of Adam Johnson, Jobi McAnuff, Mart Poom, Nathan Ellington.
"When you spend that sort of money in this league, you're taking a chance, but he's willing to do that because he wants to go up with Watford.
