The 25-year-old played a key role for Betis as they made it to the Europa Conference League final, scoring nine goals and providing five assists in his 26 games across all competitions.
Antony has opened up about his struggles at Man United, recently revealing he considered retirement as he continued to struggle at the club.
Now that he’s managed to rediscover some form and is more confident, former United goalkeeper Van Der Sar believes he should be given a second chance.
He said: "Luckily, I'm not in a position anymore to dictate at a club which kind of players have to come, but they're on the right track by signing a more experienced striker, maybe with another one on the way.
"The two players they signed in the winter break were good, so they should be fine if they give faith to the manager. "
Maybe (Alejandro) Garnacho's going to go, I would say bring Antony back, but I'm not sure if that's realistic."
