During the warm up of the FA cup forth round game between Chelsea and Ipswich on 24/01/2009 I happen to be filming when ballack boots a ball that hits a pigeon that flew across the pitch, I'm sure he didn't do it on purpose, but maybe he did. :P
The bird flew away and I guess it is ok, maybe just a headache.. Must be one strong bird. I know its not clear on the video that both birds flew off, but they did.
2 Pigeons fly across, it is the 2nd one that gets hit. If you are having problems seeing it try clicking the High Quality link under the video.
