Antony signing for Real Betis is one of their best signing their summer he was very instrumental for them during his loan time and now that he's back as a full player his presence should add more force to their attack just like he did last season. Antony performance for Betis was far better than what we saw him do in Manchester United and this season Real Betis should finish in top4 probably ahead of ATM they is in poor form.
Surely something must have motivated him to go to Real Betis. Sometimes there are factors we don't know about in the decisions of players and coaches. For example, Mourinho refused to go, despite being overpaid, to play in the Arab League. Maybe his wife doesn't like the climate or something else in that part of the world.
There are multiple factors involved when transferring to a team. The country's situation is one of the most important factors. What it offers you is also important. Although Saudi Arabia offered Jose Mourinho a very high contract, the Portuguese manager declined. Perhaps because he felt living there was unfamiliar to him. He's currently unavailable, and another offer from Saudi Arabia is likely to arrive. I don't know if he'll consider it, but if he doesn't, managing a team in Europe wouldn't be too difficult for him.
