Antony has shown quite good performance so far so of course Real Betis must take this step and it is even Real Betis's shoes to make Antony permanent because this player can contribute greatly to the team.
For now there has been no discussion too far but for Antony this is a step that will make his career progress in the future because with Betis it has been proven that he can be better and this is in contrast to when Antony was still at Manchester United.
Antony is not a too good player because he did not perform well in Brazil national team, but by showing opposite performances in Manchester United and real Betis, he shown that he was not used properly in Manchester United.
If we saw some other stories of Lukaku, McTominay and other players who left Manchester United and played better considerably, it seems there are many problems in Manchester United and not only come from their players. If they had used Antony better, he would have made more contributions for them and the club performances would have been much better too.
