"Worth the money" (as is "worldie," though I'd put Bruno, Lukaku, and De Jong on that list) is a bit more subjective than "Pepe is the worst player who transacted in this price range at that time."Only Bruno and Lukaku are the ones you can say worth the money spent on them and neither of the are worldies tbh. You may not like the player but you can't pull this as a stick to beat him with.
FWIW, I think Pepe is a useful player and should start. He just isn't and never was worth half what we paid.
