I don't know either, although I feel absolutely certain they did. And I also know for certain that signing new players is not a straightforward process by any means for the biggest, richest, best-run clubs in the world, let alone a tin-pot outfit like Cardiff City.
However, I'm not the one who keeps making these bold claims and delivering them as fact. You said: "Almost every fan I talk to realised we needed more. The club didn't..."
You're not giving opinions, you're stating these things as fact. You do it regularly, but perhaps I'm giving you more credit than you deserve. Maybe you're just not very good with the English language.
