Chelsea have handed new contracts to young trio Nathaniel Chalobah, George Saville and Adam Phillip.

Chalobah, who turned 17 last month, was on the bench against Wolverhampton Wanderers on Monday and has signed his first professional contract.

Saville, meanwhile, has committed himself until 2015 after impressing in the club's reserve team this season.

Phillip is currently out with a long-term injury, but the 20-year-old is highly rated by the club's coaching staff and could return by the end of the season.
