Current head coach Billy McKinlay is reportedly set to leave Vicarage Road after just eight days in charge, having stepped up to the role following Oscar Garcia’s decision to leave on medical grounds.
Garcia, who was appointed at the beginning of September, oversaw one game in charge - a 1-0 defeat at Charlton - before being admitted to hospital following chest pains. He was still officially in charge for a further two games, although he was absent from the action, before stepping down 27 days after his appointment to focus upon his health.
McKinlay stepped into the head coach role, having only arrived at the club in one day earlier, and he led the Hornets to a 2-1 victory over Brentford in his first game in charge. He was rewarded with a draw in his second game, keeping him undefeated heading into the impending international break.
The coach has reportedly been tempted to join Fulham, with whom he has spent a number of years as a coach, leaving the Hornets to search for their fourth manager in just six weeks.
According to BetVictor, leading the way in the race for the vacant role is Jimmy Floyd Hasselbaink, as 6/4. The former Chelsea and Leeds man has worked in a coaching capacity with fellow Championship side Nottingham Forest in the past, whilst his only managerial experience came with Belgian second division side Royal Antwerp. He put his name forward for the vacant managerial seat at Elland Road before the appointment of Darko Milanic, and he is said to have been seen visiting Vicarage Road in recent weeks.
Other favourites for the role are Tony Mowbray and Chris Hughton - both at 6/1 - whilst another former Chelsea man, and current Hercules boss, Slavisa Jokanovic, is running at 8/1, after spells in charge of Partizan Belgrade and Levski Sofia.
