Berlin: Ademola Lookman created a goal but RB Leipzig squandered the chance to go second in the Bundesliga on Sunday after crashing to a 2-1 defeat at home to bottom side Cologne.
Lookman, an England Under-21 winger on loan from Everton, shone during his 59 minutes, hitting the post in the move that led to the opening goal on five minutes at Leipzig's Red Bull Arena.
When Portugal international Bruma crossed to the far post, Lookman, 20, nudged the ball onto the woodwork and French striker Jean-Kevin Augustin tapped home the rebound.
Having scored on his Bundesliga debut three weeks ago, Lookman played well before being replaced by Danish forward Yussuf Poulsen for the last half hour.
With Lookman on the bench, Cologne roared back with two goals in the final 20 minutes.
French midfielder Vincent Koziello smashed home a left-footed shot on 70 minutes and then substitute midfielder Leonardo Bittencourt, returning after a groin injury, fired home at the back post seven minutes later.
The defeat leaves Leipzig sixth while Cologne remain eight points from safety with just 10 games left.
