Watford have signed Chelsea midfielder Nathaniel Chalobah in a £6million fee deal.

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, agreed a five-year deal and underwent a medical at the club's training ground on Thursday evening before being unveiled.

Chalobah will wear the No 14 shirt for the Hornets and Watford boss Marco Silva looks to utilise him in midfield.

The 22-year-old returns to Vicarage Road where he spent the 2012-13 season on loan.

During that spell he made 42 appearances in the Championship and scored five goals.

He played a major role in England Under 21s' recent progression to the semi-finals of the European Championship.

Chalobah played 15 times for Antonio Conte's Blues last season in the Premier League.

He made his first league start for them against Watford in May.

Shortly before Watford announced the signing, Chelsea bizarrely posted an image of Chalobah from training on Thursday.

'Heads up @chalobah,' the tweet from the official Chelsea Twitter account read with a picture of him heading a football attached below.
