The three points were vital for Manuel Pellegrini's side, allowing them to reclaim fifth place in the La Liga table. Betis now sit on 19 points from 11 matches, just three points behind fourth-placed Atlético de Madrid (22 points) and four behind Villarreal in third (23 points).
The win provides the perfect response to their previous home loss against Atlético, a direct rival for European qualification.
"It was very tough losing to Atlético at home, and that's why it was so important to win today and be up there," Antony explained. "We have many games ahead of us; we have to be patient, take it one game at a time, and keep moving up."
Antony's brace on Sunday brings his tally to four goals in his last three league matches, a red-hot streak of form that is silencing critics who have previously questioned his end product. The winger was quick to point out that his newfound clinical edge is no accident.
"I say it's dangerous because I train a lot," he said. "I practice finishing every day and it's not luck, it's training, it's work. I feel very happy to score two goals."
This dedication to his craft, combined with the clear emotional lift he has received from his environment at Betis, is paying dividends on the pitch.
