Lazio president Claudio Lotito has taken a fresh swipe at former coach Vladimir Petkovic.

The patron fired Petkovic for breach of contract - something the Coach is contesting with his own legal action - after he signed for the Swiss national team from July 2014.

"The club never interfered with Petkovic's choices," Lotito told Sky Sport Italia in an ill-tempered interview ahead of tonight's game with Bologna.

"We signed international level players. Up until now there has been a lack of tactical organisation and this negatively influenced their confidence. Evidently Petkovic had his mind elsewhere.

"Edy Reja has brought back order to the team and I hope with the new Coach things can settle."
