Walter Mazzarri hasn't even closed finished boxing up his head coach's office at Vicarage Road, but the Italian has wasted no time in unleashing both barrels on Watford in a strongly worded attack on the club's philosophies.
Speaking to Spanish news website MarcadorInt, Mazzarri said the Hornets "do not have the same ambitions" as his former clubs, including Inter Milan, Napoli and Sampdoria, and added his attempts to instill a winning mentality at Vicarage Road had fallen on deaf ears.
The astonishing interview comes following a season of often uninspiring football and formations from Mazzarri himself, although the head coach did feel he had done well by managing to keep the Hornets in the Premier League.
"It has been a great experience, I am very happy to have lived it," he said. "It has been interesting to see English football from within. We have had some problems, but we have met the target.
"In addition, we have been able to win difficult teams like Arsenal, Manchester United or Everton. It was a shame that right at our best, when everything was going well well, when we were seventh, we had an incredible accumulation of injuries.
"Despite these misfortunes, we were able to reach 40 points with six games remaining of the season, which is the record for this club.
"As we fulfill the goal of survival in advance, it is normal that from there the players will relax. This club does not have the same ambitions, the same mentality, as the previous clubs in which I have been.
"I tried to instill a winning mentality here, but between the injuries and the difficulties that have come at the end of the season, it has not been possible."
Mazzarri interestingly singled out Daryl Janmaat and Abdoulaye Doucoure as players he had worked with especially closely to improve their technical and mental capabilities during the campaign.
Both have undoubtedly been two positives for the Hornets on the pitch, with Doucoure outshining his midfield colleagues in recent weeks and Janmaat yet to record a below-par performace in a Golden Boys shirt.
He also appears to have already grown tired of any desire to remain in England in the short-term, a year after cracking the Premier League was cited as his main motivation behind joining Watford.
Mazzarri specifically namechecked Spain as a potential destination - which would go some way to explaining his interview with a Spanish newspaper, having never managed in the country nor played there in his career.
He said: "When I finished my last stage in Italy, I felt that my motivation had reached a peak and I came to England. I needed new challenges.
"Now I would go to Spain, Portugal or any other destination that motivates me. If possible, I would like to know a new league. The most important thing is that it is a club that stimulates me. A challenging project.
"It does not have to be a very big club; I am willing to accept any position if I can feel that the project is going to be mine. I do not want to walk andare, but I want to choose a project that appeals to me.
"It does not have to be a very big club; I am willing to accept any position if I can feel that the project is going to be mine. I do not want to just go anywhere, but I want to choose a project that appeals to me."
