Watford chairman Graham Simpson is confident Adrian Boothroyd will remain at Vicarage Road.
Boothroyd has attracted the attention of top teams by leading the club to the Coca-Cola Championship play-off final against Leeds in his debut season as manager.
Should the Hornets clinch a place in the Premiership next Sunday, his stock will be even higher.
But Simpson told BBC Radio Five Live's Sportsweek programme: 'He wants to build something at Watford.
'He is an exceptional man and recently signed a four-and-a-half-year contract.
'Adrian is a man of his word. I do not believe he will suddenly move elsewhere.
'He needs the experience and he needs to learn.
'We are a very progressive club and are building on and off the field. There is no reason why Watford cannot grow and grow.'
Simpson insists his players will be the underdogs in Cardiff.
He said: 'Leeds' wage bill is three times above us. We are a very young team punching above its weight.
'But we have a very good manager and are very focused.'
