Zoopla can do what they want with their sponsorship. Personally, if I was the Jewish co-owner of a company, and saw my brand all over the media emblazoned on the shirt of a footballer making anti-Semitic gestures, I think I'd drop the sponsorship too.
As for the FA, they have no choice - they are trying to eradicate racism from football. It's no different to, say, a West Brom player calling a Spurs player a f***ing Y*d within earshot of the crowd - what do you expect the FA to do, let it pass without comment?
