Michy Batshuayi had a debut to remember as his two goals gave Borussia Dortmund a much-needed victory over basement boys Cologne.
Batshuayi's strikes, coming in the 35th and 62nd minutes, were cancelled out by Simon Zoller and Jorge Mere respectively before the outstanding Andre Schurrle scored Dortmund's winner six minutes from time.
Batshuayi, who arrived from Chelsea on loan as Pierre-Emerick Aubameyang departed for Arsenal, turned provider for the winner in an outstanding debut which should give the Belgian plenty of confidence.
"I am very happy with my two goals but of course the most important thing today is the win," he told German Eurosport.
