Watford reportedly chose not to appoint new Barcelona boss Quique Setien before appointing Nigel Pearson as manager last month.
Former Real Betis coach Setien signed an 18-month deal with Liga leaders on Monday after Ernesto Valverde was fired from the club.
Second The evening standard (via The Sun), the Spaniard is believed to have been among some candidates to interview for the Hornets’ executive work in December.
The vacancy came after former manager Quique Sanchez Flores was fired following Watford’s 2-1 defeat against Southampton.
However, the 61-year-old is said to have been unsuccessful as Nigel Pearson got the best job and has since overseen an extraordinary turnaround on Vicarage Road.
Pearson took the lead with the Watford Premier League fund, but relieved the club of the relegation zone after taking 13 points from his first six league games.
In the meantime, Setien was officially introduced on Tuesday as manager of Barcelona and admitted that his appointment went beyond his “wildest dreams”.
“Yesterday I was walking around my hometown with the cows around me and now I’m here in Barcelona managing the best players in the world,” he told reporters during his first press conference.
“I want to thank this institution for giving me the chance.
“Not even in my wildest dreams could I have imagined it. I have to thank the club. I am thrilled with this challenge and this project.
“This is the biggest thing I have to pass on to the players. I have to show it to the players and normally it’s not very complicated to pass it on.
The 61-year-old, who also managed Racing Santander and Equatorial Guinea, arrives at Camp Nou with Barcelona leading the Liga, ahead of Real Madrid’s bitter rivals on the goal goal.
He will be on the bench for the first time when his team hosts Granada on Sunday.
“I thank Ernesto Valverde for leaving me with a team that is at the top of the ranking,” added Setien.
“My goal is to win everything. Everything you can win, this club has no other path to follow. Year after year, to win as many trophies as possible.
“I think the best way to win is to play good football. It doesn’t always happen, but it’s not just a day, but to continue.”
