The competition to be the biggest regret of Chelsea's is a hot one. Dominated by the Mohammed Salah, Kevin De Bruynes and Romelu Lukaku of a previous world, there is a new wave of players that weren't just sold for cheap. They were produced and let go too soon.
Often spoken about is Declan Rice, but joining that list could also be Tino Livramento, Marc Guehi and possibly Levi Colwill, depending on how Thomas Tuchel plays next summer. This is all without considering the players that have played for Chelsea more recently but gone on to be sold.
There's a new competitor now, though, and a £126 price tag could take the top spot in this mini battle.
