A lot of the opinion at the time of Gyökeres' signing was that he was signed to compete with Havertz.
Signing a £60m striker who's not a guaranteed starter is pretty normal Champions League contender business these days. Wissa, Ekitike, Woltemade, Šeško, Eze, Solanke etc, all in that ballpark ... it's just the cost of players now. Even Nketiah moved for £35m.
