text: did anyone see marcos senna playing with blood on his trousers in the champions league against inter? what the hell happened there? that was very odd and i havent seen anyone reporting on it i read some reports that said that senna was injured when engaging in a tackle with inter player wome. one of wome's spikes inadvertently caused a cut in senna's groin area, causing the blood which we all saw. he had the wound stitched up and was fine.
