The term "selling club" is usually used to describe a club, like Ajax or maybe Southampton that sells its best players. We don't do that. Tony has consistently fended off bids for players he wants to keep over the last few years (though who knows, maybe that will change). Selling youth...
We haven't actually sold someone we wanted to keep for years so on that measure, no we're not a selling club. I might say something different after the transfer window has closed.
In any case, the fact that we have players that other teams want, I'm taking as a positive. It wasn't forever thus
