Watford have signed Manchester United midfielder James Garner on a season-long loan.

Garner, 19, started three Europa League games for United last season and has played seven first-team matches in all since his debut in February 2019.

Garner captained England Under-17s during the 2018 European Championships, reaching the semi-final stage.

He could make his debut for the Hornets in Saturday's away league game at Sheffield Wednesday.
