Yes, you're right, and Antony really found a great environment at Real Betis, which made him very eager to join this La Liga club. He even said that he rejected an offer from Bayern Munich because he only wanted to go to Real Betis. Wow, he was on loan at Betis last season for a few months and has found his home.
Antony prioritizes performance and comfort so it is not surprising that he prefers Real Betis even though the salary is lower, we also saw Antony's performance was very good when he played there and the support from the fans made him want to stay. In 2022, Manchester United spent 95 million to bring in this player but this year they only released it for 22 Million even though I'm sure Manchester United would get a better price if they let him go to another team, it's just that Man United don't have many options.
