Caleb Wiley is on his way back to Vicarage Road.

Wiley has rejoined EFL Championship side Watford on a season-long loan from Chelsea, both clubs announced Tuesday. The American fullback spent the second half of last season at Watford, earning important playing time in one of Europe’s tougher leagues.

“We are delighted to have secured Caleb on loan once more,” said Sporting Director Gian Luca Nani. “He was impressive in the games he played for us last season and his attitude is incredible.

“To have him for a full season means we have the talent and consistency Paulo wants defensively,” Nani added. 

Wiley overcame a shoulder injury to make his Watford debut last March. He proceeded to make 10 appearances for the club under Tom Cleverley’s tutelage, registering two assists. 

Prior to his move to Watford, Wiley spent the first half of the European season on loan at Ligue 1 side Strasbourg. 

The 20-year-old originally came up through the Atlanta United ranks and has earned three caps with the U.S. men’s national team to date.

Watford opens the 2025-26 season at Charlton Athletic on August 9.
