Lord Doherty said in his opinion the prospects of Khan succeeding in an appeal against the FFT ruling were "fairly poor", partly because of his relatively low integration into Britain and his strong connections with Germany.

The FFT added in a statement released to Press Association that it "would be very sad for Richard Gasquet himself, for tennis in general, for French tennis in particular, whose image would be dented" if the positive test was officially confirmed.
