Centre-back Mats Hummels scored twice as Borussia Dortmund won 2-0 at Arminia Bielefeld to remain top of the Bundesliga alongside Bayern Munich on Saturday.
Hummels was in the right place to fire the opener from a corner by England international Jadon Sancho seven minutes after the break at the Bielefelder Alm.
Former Birmingham midfielder and Manchester United target Jude Bellingham had a strike ruled out for offside ten minutes later.
Germany defender Hummels then sealed the win when he headed home a Marco Reus cross with 19 minutes of normal time remaining.
