Kanga had one season at Hertha Berlin. His stats were 15 (+8) appearances, 2 goals. Hertha finished rock bottom of the Bundesliga and were relegated.
It would be good to know why they then decided to loan him out to Liege as opposed to giving him a chance in the German second tier, but I don’t suppose we ever will.
This could hardly be described as an impressive signing, but it is an interesting one. Kanga has shown in Switzerland and Belgium that he can score goals, but his career thus far has been erratic. Hopefully, Championship football will suit him better than French, Turkish or German football did.
