Lazio are apparently destroying Mauro Zarate by playing the striker out of position, according to his brother and agent Sergio.
Edy Reja chose to shift the Argentine out wide against Palermo at the weekend and Lazio won 2-0 thanks to a brace from Giuseppe Sculli.
Speaking to Radio Mana Mana, Sergio Zarate said: "I still haven't spoken to Maurito, but I am not happy with the position that he played against Palermo.
"He's not a full-back for Christ's sake. He played 5m from Radu on Sunday. He was almost always close to Muslera's goal.
"We'll never see the real Zarate this way. Lazio are destroying him like this.
"We still have three years left on Mauro's contract with Lazio and we want to respect it at least until a team ready to do a deal with Claudio Lotito arrives.
"This is another story."
