Chelsea starlet Nathaniel Chalobah has left the club on loan once again.

The 19-year-old is set to embark on a short-term stint with Middlesbrough, after previous spells with Watford and Nottingham Forest in the second-tier of English football.

Despite his early breakthrough at Chelsea, where he featured in a first-team squad at the age of 15, the versatile defensive-midfielder is yet to make a Premier League appearance for the club he joined as a boy.

"Nathaniel Chalobah has today (Thursday) joined Middlesbrough on loan until the end of the season,” read a statement on the Blues website.

"Chalobah, who can play in midfield or the centre of defence, was first involved with Chelsea's first team as a 15-year-old in September 2010. He was named among the substitutes for our League Cup clash against Newcastle United."

Capped at multiple youth levels for England, the teenager penned a new five-year contract at Stamford Bridge back in August following the arrival of Jose Mourinho in the summer.

And, one of his initial rises to prominence came under the tutelage of Chelsea legend Gianfranco Zola during his spell at Vicarage Road, where he helped the Hornets reach the Championship play-off final.

With such strong competition for places at Chelsea, it's no surprise to see Chalobah leave once again, and he joins teammate Kenneth Omeruo at the Riverside.
