I don't think it will do that well in the UK or America. I don't think Khan is that popular in America and I don't think casual fans in the UK will be too interested. If it was Brook vs. Khan on Sky it would probably do over 1 million buys in the UK alone even though it wouldn't be very popular in America. Khan would have got more money for Brook. I suppose that option is still there but I don't think he fancies it.
