Lazio president Claudio Lotito says they're determined to keep hold of coach Vladimir Petkovic.

Lotito does not think the Bosnian is looking to leave.

"Petkovic is under contract with us, and I consider him to be a good person, a serious professional," said Lotito.

"I don't think he is feeling badly at Lazio, and I don't see why he would want to leave.

"We are ready to extend his deal. I would like to end the habit of people contacting players or coaches under contract, because these are not sport's values. The important thing is that rules are always respected."
