Ferdinand wrote in his column for the London Evening Standard: "He's taken a lot of stick this season but his goal and all round performance against Arsenal proved he can cut it in the Premier League.
"At the time when we needed him to start showing his best form, he is doing that. He is tracking back and working hard as well as being influential on the ball. He could be one of the reasons why we stay in the Premier League if he can deliver the same level of performance for the rest of the season.
"Adel has bags of talent and it's amazing it took him that long to score his first goal in the top flight. He's always difficult to face in training and I know he can cause problems for even the most assured of defenders."
