Maybe, but thought Sanchez was the record still (even adjusting, CB generally cheaper than high end 10), from before the new stadium.didnt gio break the record then ndombele shortly after? gio was big money at the time for 40m or whatever he was. gio and ndom was meant to take us to the next level.
Both combined were of course the true “never done that before”, but also hugely diluted as we just made the CL final (paying half their fees instantly!).
