It’s never been about that. It’s about actually addressing the identified holes in your squad and taking a chance on a solution rather than saying the one guy we want isn’t available so we’ll do nothing. Year after year there are bids for players in certain positions, a failure to sign them and then nothing.
That summer we only signed Cech I’m pretty sure wasn’t a summer where we only attempted to sign Cech. We bid for Gotze and got Ozil, we bid for Hazard and got Cazorla, but we supposedly bid for Xhaka, Lacazette, Draxler, Mbappe, Lemar, Bender and decided to sign nobody instead (could argue Laca stopped Mbappe I guess). Not even attempting to improve when you’ve identified a weakness is not ambitious.
