Watford have agreed an £6million fee with Chelsea for midfielder Nathaniel Chalobah.
The 22-year old was offered a new contract at Chelsea but wanted to play more regular football and has opted to move to Vicarage Road.
Chalobah, who also had interest from Southampton and Swansea City, has agreed a five-year deal and underwent a medical at the club's training ground on Thursday evening.
Chalobah will wear the No 14 shirt for the Hornets and Watford boss Marco Silva looks to utilise in midfield.
