We also have distanced ourselves as part of negotiations, when the price is too high. So not distancing ourselves could well mean we aren't at it at all. What we haven't done, is gone and distanced ourselves from every single player linked with us, so there is just as much chance, if not more, that not coming out denying speculation means we aren't interested, than that we are.
Transfer window mate, anything can mean anything. Most often, we make it fit what we want it to mean.
Fyi I'm not really arguing we arent interested in Kane, just that not publicly claiming so doesn't mean we are.
