Chelsea defender Andreas Christensen has joined Borussia Monchengladbach on a two-year loan deal.

The 19-year-old made three appearances for the Premier League side last season but will now reunite with former Blues starlet Thorgan Hazard, who joined the Bundesliga side on a permanent deal in January.

Chelsea confirmed the move via their official website, with Monchengladbach claiming the player will remain at the club until June 2017.

He becomes the second Chelsea youngster to leave the club in a day, following Josh McEachran's permanent move to Brentford.

But while Chelsea have allowed two youngsters to leave, more have arrived at the club's academy including 16-year-old Joseph Colley, who has been given a contract after coming through the ranks of Swedish side Brommapojkarna.

Christensen made his move to Stamford Bridge as a 16-year-old and while he remains highly thought of by the staff at the club, most of his playing time has come with the Under-21 ranks.

Monchengladbach appear to be prepared to offer him a first-team role, with sporting director Max Eberl telling the club's official website: "Andreas Christensen is a promising talent and can cover a variety of positions in defence. We're delighted that we've been able to bring him in on loan from Chelsea."

Christensen leaves the club for the first time on the same day a veteran of Chelsea's loan system leaves on a permanent basis. McEachran, who has signed a four-year deal with Brentford, had five spells on loan away from west London in three years but despite being tipped as a future first-team player following his debut in 2010, the club have seen fit to allow him to leave.

Winger Christian Atsu has also left the club, joining Premier League new boys Bournemouth on a season-long loan. Mario Pasalic, who only joined the club in the summer of 2014, has also left on a temporary deal, joining Monaco in Ligue 1 as part of the deal that saw Radamel Falcao sign on at Stamford Bridge.
