BERLIN, Nov. 2 (Xinhua) -- Yuya Osako's brace helped Cologne overpower Bate Borisov 5-2, while Hertha Berlin moved 2-0 past Zorya on double strikes from Davie Selke in the fourth round of the Europa League group stage on Thursday.
The Billy Goats have reaped their first win in Europe after crushing resilient Bate Borisov on four second-half goals in Group H.
Cologne secured a bright start in front of the home crowd as Simon Zoller opened the scoring after capitalizing on a through ball from Salih Oezcan 16 minutes into the game.
The visitors from Belarus stayed strong and responded in the 31st minute through Nemanja Milunovic, who tapped home a free kick from Aleksei Rios to restore parity.
Bate gained momentum and turned the tide after Rios' pinpoint cross found Nikolai Signevich, who made it 2-1 on the scoreboards with an overhead kick two minutes later.
Cologne wobbled and needed half time to recover from Bate's comeback. However, it took the "Billy Goats" nine minutes in the second half to level the scores as Bate failed to clear the ball from the area, allowing substitute Yuya Osako to slot home from close range.
The hosts gained momentum and grabbed the lead for a second time as Sehrou Guirassy unleashed a free-kick hammer to get his name on the score sheets in the 63rd minute.
Cologne weren't done with the scoring, and added another two goals through Osako, who sealed his brace in the 82nd minute as well as through Milos Jojic, who headed home the 5-2 lead in the dying minutes of the game.
