Shinzo Koroki punished his former teammates with a hotly disputed goal as Urawa Reds came from behind to beat Kashima Antlers 3-1 on Saturday night.
Koroki, who joined Urawa over the winter after eight years at fierce rival Kashima, gave the home side a 78th-minute lead after Daisuke Nasu had canceled out Takuya Nozawa's opener, before substitute Tsukasa Umesaki made the game safe with a third in the 89th minute.
Two Antlers players were booked for protesting that Koroki's goal was converted from an offside position, but the scorer himself was in no mood to complain after Urawa used the win to leapfrog Kashima into third in the J. League table.
