Chelsea boss Antonio Conte is keeping hold of Andreas Christensen.
It's been confirmed the Dane will stay with Chelsea this season and wear the No27 shirt.
Christensen has been away from Chelsea these past two seasons with Borussia Monchengladbach.
"I've played 80 matches in the last two seasons and have achieved a lot of consistency," the defender said of his time with Gladbach.
"I have been hardened, perhaps more mentally than physically."
