The agent and brother of Mauro Zarate insists the Lazio striker has nothing to prove to Roma captain Francesco Totti tonight.

Ahead of the Rome derby, Totti questioned the quality of Zarate and the hype surrounding the Argentine.

"Mauro told me he will score against Roma," revealed agent - and brother - Sergio Zarate.

"He dreams of giving the victory to the fans? As for those comments, he already silenced Totti last season."
