Thorgan Hazard has backed teammate Andreas Christensen to make a big impact at Chelsea when he returns from his loan at Borussia Monchengladbach.
Christensen, a Danish centre-back, has flourished in a two-year stay with the Bundesliga club.
And Hazard is in no doubt that the 20-year-old can make the step up when he goes back to Stamford Bridge in the summer.
"When he arrived everybody in the team and at the club were saying: 'Wow, what a defender, what a player,'" he told Goal.
"He is strong, he is fast, he is intelligent and so he has helped us a lot and helped us get Champions League qualification.
