The point is, if Willian stays on, we would have practically have at least 2 players in each of the attacking position already (LW, AM/No.10, RW and ST). Adding Havertz would just be overkilled at that point. IF Willian does stay on, then I would sure as hell rather see the club spend that money on improving the defence because I do not want us to spend another season complaining about the shitty defence costing us games again and ultimately, the chance to win trophies.
