Most budget-shattering signings at Real Madrid are judged on, among other things, how they perform in Clasicos. It will never cease to be staggering that in four seasons Eden Hazard never played in a single one in Spain.
He has been the club's top earner, on around £400,000-a-week, since he joined in 2019 with the job of filling the void left by Cristiano Ronaldo.
No one questioned the signing at the time because Hazard was coming off the back of a season in which he had scored 21 goals for Chelsea leading them to Europa League success.
