Eintracht Frankfurt came from behind to snatch a controversial 2-1 home win over lowly Energie Cottbus in the Bundesliga.

Cottbus, who beat leaders Bayern Munich last weekend, took a 48th minute lead when Eintracht keeper Oka Nikolov allowed a seemingly harmless 25-yard shot from Timo Rost to slip through his hands.

Brazilian Caio levelled from 18 metres out after a neat one-two with Czech striker Martin Fenin, but there was controversy in the 65th minute over whether the ball had crossed the line when defender Marco Russ struck the winner.

Cottbus keeper Gerhard Tremmel dived to his right to parry Russ's shot and the ball hit the post before bouncing back down the goal line before being smothered by Tremmel.

Referee Michael Kemptner showed no hesitation in awarding the goal but television replays appeared to show that only part of the ball had crossed the line.

Frankfurt moved up to sixth place with the win, while 15th-placed Cottbus are just above the drop zone.
