Youssoufa Moukoko’s powerful header gave Borussia Dortmund a 1-0 victory over local rivals Schalke 04 in the Ruhr Valley Derby on Saturday to send them top of the Bundesliga.

The 17-year-old headed in at the far post in the 79th minute to take Dortmund to the summit on 15 points and become the youngest ever scorer in a Ruhr Derby.

There was bad news for the hosts, however, as their captain Marco Reus was carried off with what looked like a serious ankle injury after a collision with Schalke’s Florian Flick.

The Germany international, who was called up for this month’s Nations League matches, turned his ankle and had to be treated on the pitch for several minutes before being taken off in the 32nd minute.

Reus sat out 2014 World Cup-winning run after being injured in the final warm-up game before their departure to Brazil.

He also missed Euro 2016 due to injury.

Bayern beaten

Champions Bayern Munich suffered a shock 1-0 loss to hosts Augsburg to stretch their winless run to four consecutive league matches and drop to fourth place.

Mergim Berisha slotted in a cutback with a composed finish in the 59th minute to seal the three points and pile more pressure on Bayern coach Julian Nagelsmann.

His team have now drawn three and lost one of their last four league matches.

It was the first time in 87 matches that Bayern had failed to score in a league game and the first time in 20 years that the team had gone four league games without a win.
