I have heard some rumors regarding Real Betis' plans for Paddy Antony, Several sources say Real Betis will take advantage as the transfer deadline approaches so this way they can bring in Antony at a cheap price. On the other hand, Manchester United released Antony to another team at a high price, but Antony only wanted to move to Real Betis well Real Betis and Antony seem to play the same role. We don't know how this drama will end and I suspect Manchester United will agree to Real Betis' offer.
This would be a much better option, but I'm very confident Manchester United won't let Antony go for anything beyond the agreed price.
Antony has indeed expressed his desire to play for Real Betis permanently, but selling him at a low price would be detrimental to Manchester United, so they won't let him go.
This should be the case so Antony has the opportunity to continue his career at Real Betis, rather than staying at Manchester United without playing time.
