Real Madrid legend Zamorano: Martino bringing out best in Barcelona's Alexis Sanchez
Sanchez hit a hat-trick in victory over Elche on Sunday.
Zamorano credits the form revival to Barca coach Tata Martino: "It shows that he has earned Martino's trust. Certainly to succeed you must fight against everything, but the coach's support will always be crucial.
"It's huge what Alexis is doing today in the Liga. He's going through a great moment, the best since arriving in Spain.
"Alexis has grown as a player, has learned much in his European experience and today has more scoring ability as a result of that."
