Nathaniel Chalobah signed a five-year deal at Vicarage Road in July 2017, joining for an undisclosed fee from Chelsea.
On the October 15, 2018, Nathaniel Chalobah became the first Watford player since John Barnes in 1983 to play for England. He was a stoppage-time substitute in England’s 3-2 away win against Spain in the UEFA Nations League group stages.
The midfielder has also played 97 times for England at various youth levels, and he was a key part of the Under-21s’ recent run to the semi-final of the European Championships.
The 22-year-old initially excelled during 42 appearances while on loan with the Hornets during the 2012/13 season, scoring five goals.
Since then he has spent temporary spells on loan from Chelsea with Nottingham Forest, Middlesbrough, Burnley, Reading and Napoli, before returning to the first-team fold at Stamford Bridge.
He featured 15 times for Premier League champions Chelsea during 2016/17, making his first league start for the Blues against Watford at the back end of the campaign.
He made a positive start to the 2017/18 season – appearing in the Hornets' first five games before injury disrupted the rest of his campaign. He did return, however, making a short cameo appearance on the final day of the season against Manchester United.
The 2018/19 season saw Chalobah play back-up to Étienne Capoue and Abdoulaye Doucouré, with the French midfield duo proving very difficult to dislodge with a series of stunning displays throughout the campaign.
Chalobah appeared 26 times during 2019/20, scoring once.
