Cologne beat their local rivals Bayer Leverkusen in the Rhine derby thanks to two goals from Dominic Maroh.Leverkusen, who saw their Champions League campaign suffer a setback with a 3-2 defeat to Roma in midweek, fell behind to Maroh's volley in the 17th minute.Javier Hernandez levelled matters with a header in the 33rd minute, but a red card for Kyriakos Papadopoulos hardly helped their cause.Maroh went close to giving Cologne the lead again just a minute before he did find the back of the net for the second time, with a header from Marcel Risse's cross.It was enough for all three points as the Goats moved above their hosts and rivals to seventh in the Bundesliga on Saturday.
