Madrid wouldn't sell him to Sevilla. Lopetegui insisted on having him and Perez said no. Don't change facts to suit the narrative. He was dreadful tonight, but, just like Bergwijn, he's been a victim of dreadful coaching.
Or just maybe neither are very good in the first place.
If Reguilon was ever this world-beater of a left-back you're trying to make him out to be he wouldn't have signed for us, and certainly not for 35 million.
