They were unbeaten in their first 15 games, but the result declined after losing 2-1 to Cardiff on December 29 to take only five points from their next nine games.
Spanish reports in Spain earlier this season are reported that former Villarreal president Jose Rojo Martin, known as Pacheta, has been in talks with Watford to replace him.
In January, the club refused to support him as “pure stupidity” and his owner Gino Pozzo later.
Last week, Clevely said hopes for a hamstringer had been hampered with injuries, especially among his strikers.
“There is no difference in the number of goals they have acknowledged before January to January, but the amount we have scored has fallen significantly,” the Spaniard said.
He promised to learn the campaign lessons and added: “We spent 10 weeks in the ranks (putters), before the year’s turn, we showed the true positive sign and I think we can clearly identify where and why we are a little steam.
“We have a young unbelievable young compound, the average age of one or two people increases, but in addition, it is significantly under the age of 25 and most of them are under the age of 21 in the course.
“The experiences they had this year – some bad – to really develop and eventually be better than one of the most attractive positives of this season.
No Watford manager or coach has spent a year’s calendar after the 2010 king Makai.
Since the 2022 Premier League relegation, they are 11th and 15th and are now 14th.
“There will be no other statement of the club until a new time is set,” a statement said.
