Let's be honest, the hard yards for the acquisitions of Vardy, Mahrez, Kante, Drinkwater, Fofana, Maddison were done by our scouting network. Steve Walsh played a huge role. Crucially, out of that group, only Fofana and Maddison had serious interest from clubs of our status at the time - and were promising the roles we did. So when it came to negotiating the deals, it didn't exactly require genius-level brain power. For Mahrez, Vardy and Kante coming to us was a step up at the time. For Drinkwater, a very welcomed fresh start.
Getting the money we did for Fofana, Maddison, Barnes, Maguire, Mahrez, Chilwell and Drinkwater was great, undeniably. But again, for nearly each of those you can name a player who we let leave for free, who we could've received money for...Tielemans, Soyuncu, Amartey, Ayoze, Benkovic, Slimani, Soumare (contract ends this June).
As we have failed to move any player surplus to requirements out in the past 8 months, it is also undeniable that we have an issue in negotiation deals. I appreciate that this window has been difficult with the well-documented PSR issues. But for us, the utter inability to get players out in time before their contracts end, or when we no longer need them, isn't a new thing.
