Five more Watford youngsters have been sent out on loan, after their signings were announced by their new short-term clubs.
Colombians Jaime Alvarado, Eduardo Montenegro, Juan Becerra and Luis Suarez, whose signings were never formally announced by the Hornets, will all turn out for Spanish second-division side Real Valladolid next season.
Elsewhere Pervis Estupinan, a 19-year-old Ecuadorian left-back, could come up against his Watford team-mates after agreeing a season-long loan UD Almeria, who play in the same league.
Here's a brief profile of each of the quintuplet:
Jaime Alvarado
Came through a Udinese football academy based in Colombia, before signing for Watford last summer, and was loaned to Granada for the rest of the season in January.
A holding midfielder, he has already played for Udinese's youth sides as a youngster.
On signing for Watford, he revealed his inspiration in the game, saying: "I am a player who likes to recover the ball and be precise when delivering it. I really like the way Sergio Busquets plays."
Eduardo Montenegro
Another one to come through the Udinese academy, Montenegro nearly missed out on his dream of becoming a professional footballer through indiscipline and tardiness.
But after cleaning up his act, he was hailed as one of the biggest success stories of the academy since it opened in 2014.
On signing for the Hornets, his father said: "From his birth his obsession has always been the ball. From the age of five, he participated in little football schools and there he was evolving.
"The path has been chosen and thanks to God has brought him to this. It has always been a responsibility to support him, which has a little limited, because I am a worker, but we have always supported him."
Juan Becerra
The 19-year-old has earned the title of "El Tanque", and moved across from Granada B earlier this month.
Another graduate of Udinese's Colombian football academy, he spent some time training with the Italian club in pre-season before his Watford move was confirmed.
He scored 16 goals for the Granada youth side side in the equivalent of the English Under-18s league last season, ending as their top scorer.
Luis Suarez
Like his Uruguayan namesake, the 19-year-old is a goal-hungry striker, who began his career with Itagui Leones in Colombia before moving to Granada B last summer, and later Watford.
He scored five goals in 35 appearances for the Spanish third tier last season.
Pervis Estupinan
Estupinan moved to Watford last summer on loan from Udinese and spent time with Granada earlier in 2017, before a permanent move (in name at least) to the Hornets this summer.
Despite his position as a left-back, he also has four goals in 12 outings for his country's Under-20 side, including against the age group sides of Brazil and Argentina.
