Antony really wants Betis's move, but his club can't reduce his price. That's the reason his move is not happening yet. He's still patiently waiting for Betis to sign him. However, it may take longer caused by Betis can't afford his price. Betis needs to negotiate with MU to reduce his price.

I hope MU will let him leave with the discounted price. Don't be surprise if you may not see his move to the Betis in summer.
