Mauro Zarate is determined to score in the Rome derby for new club Lazio.
"I haven't spoken to (coach) Delio Rossi yet. I know we have many great strikers and I need to work hard to find a place in the team.
"I'm similar to Rodrigo Palacio (Boca Juniors). I know Lazio were also interested in him and I'm grateful they chose me."
