Quique Sanchez Flores is locked in talks with Premier League new-boys Watford.
The Mail on Sunday says the Spaniard was at the club's Colney training ground last week to look around facilities.
Talks over a new contract with head coach Slavisa Jokanovic had failed to find a solution.
The Serb wanted a rise on the £3,000 a week deal he agreed last year and was made a verbal offer of £500,000 a year to lead Watford in the Premier League.
