FRANKFURT, Germany (AP) - Cologne took advantage of terrible defending by Eintracht Frankfurt to win their Bundesliga match 4-2 on Sunday.
In the late match, Son Heung-min scored twice to help Bayer Leverkusen win 3-0 in Paderborn, which sank to 16th after its fourth straight home defeat.
Substitute defender Kyriakos Papadopoulos opened the scoring in the second half and Son completed the victory. Paderborn has only one win in the last 14 matches and could drop into the second division after only one season in the top tier. Leverkusen stayed fourth.
Cologne finished with 10 men but had earlier made sure of its second home win of the season.
Eintracht central defender Carlos Zambrano appeared to be fouled on Cologne's first goal, as the ball fell kindly to Deyverson, who scored his first league goal by lobbing goalkeeper Kevin Trapp in the first half.
Alexander Meier had his first effort parried but he sent the rebound into the net as Eintracht pulled level in the 58th.
Marcel Risse restored Cologne's lead and Zambrano then twice lost possession for Yuya Osako and Athony Ujah to score in quick succession.
Cologne's Kevin Wimmer got a red card for pulling down Haris Seferovic in injury time and Meier converted from the spot for his league-high 18th goal.
