The agents of Mauro Zarate insist there's no problems with the Argentine signing permanently with Lazio.

Lazio president Claudio Lotito revealed this week that he'd opened negotiations with Qatar's Al Sadd about an outright deal for Zarate.

And the young striker's brother and agent, Sergio, told Corriere dello Sport: "Yes, there is already an agreement with the club for the next five years. If Lotito confirms what was said, he will remain in Rome 100 per cent."

Meanwhile, it's understood the agent of Goran Pandev has put off talks over a new Lazio contract until later this season.
