The Spanish striker, who joined the Gunners from Deportivo La Coruna last summer, is looking for an exit after spending most of his time on the bench last season.
Benitez said: "I like the player because I have good friends in A Coruña.
"I know that he did really well. He's come here and not played in many games, but I like the player."
La Coruna have also reportedly expressed an interest in re-signing the 28-year-old.
