Bundesliga, gameweek 13: Preview, stats and key matches

Dortmund saw Youssoufa Moukoko become Bundesliga's youngest scorer but his historic strike was in vain as the visitors were beaten 2-1 against Union Berlin.

Dortmund suffered their fifth defeat of the season and have lost three of their last five league games.

Moukoko's goal makes him a year and six days younger than Florian Wirtz, the Leverkusen prodigy who previously held the record.

With a 100% record at home, Leipzig will want to maintain the run when they take on FC Koln.

Leipzig are on a six-game unbeaten run in the league and are the favorites against Cologne. Meanwhile, Cologne, who are placed 15th, have the best away record of any team in the bottom third of the table (W2, D2, L1).

Leverkusen have been terrific this season, going unbeaten in the first 12 games.

With eight wins and four losses, Leverkusen (28 points) would prove to be a tough nut to crack for champions Bayern.

The Bavarians trail Leverkusen by a point and a win will help them surge ahead.

All eyes will be on Robert Lewandowski, who has smashed 15 league goals already.

With four draws in their last five matches, Gladbach need three points to get started once again.

Having said that, the hosts need to sort out their leaky defence, which has shipped in 20 goals.

They face Hoffenheim, who have lost their last two games and have similar issues at the back.

It will be mighty three points for Gladbach if they show character.
