Watch: Serhou Guirassy - Delivering for Dortmund
Five days after being smashed in Stuttgart, Borussia Dortmund found themselves two down at home to local rivals Bochum. Then Serhou Guirassy scored the first of his two goals on the night to spearhead a battling turnaround derby win. Having arrived in the summer carrying a knee injury, the Guinea international is now well and truly up and running with four goals in as many appearances in all competitions. His name is ringing out around the Dortmund stadium, ever louder and more frequently.
