The midfielder proudly wore the captain's armband and rifled home on 18 minutes, a lead the Danes held until five minutes from time, when Joshua Kimmich equalised for the world champions.
Christian took his Spurs form (eight goals, 15 assists in the Premier League) onto the international stage in Copenhagen.
He'd already set-up a golden opportunity for Jannik Vestergaard - tipped over point-blank by Kevin Trapp - before opening the scoring. Denmark's high press force Germany into a defensive mistake and Christian latched onto the loose ball, drilling low past Trapp from 20 yards.
Christian went close again from 25 yards five minutes into the second half before departing on 65 minutes.
