Anthony Ujah came off the bench to score the only goal as Cologne defeated Werder Bremen 1 - 0 in the German Bundesliga on Friday night.

It was an inspired substitution by manager Peter Stoger, with the Nigeria international spending 68 seconds on the pitch before he grabbed the match winner in the 59th minute.

Ujah will be hoping that his strike against Bremen has sent the right message to the coach after failing to start in the league since the 2 - 0 loss to champions Bayern Munich late September.

His other goal in the topflight this term was scored against Stuttgart on August 30.

The prolific marksman has totaled 55 goals in 118 appearances for the teams he has appeared for - Lillestrom, Mainz and Cologne.
