Lazio coach Vladimir Petkovic is demanding victory against FK Mura in their Europa League qualifier.
The Biancocelesti won the first leg 2-0 in Slovenia last week, but their Coach does not want to run any risks.
"I expect character from the team. The psychological approach will be crucial, as we must win and do so convincingly," said the Coach in his Press conference.
"We are the favourites tomorrow, but we have to prove on the field that we deserve that title. Inter were favourites in the last round, but they ran into huge problems with Hajduk Split.
"This is not the first time that Lazio have played in the Europa League, so we have the experience to know that playing in an important match means focusing on the mental attitude, because physically we are ready.
"Miroslav Klose will rest until tomorrow, then I'll decide on the line-up in the morning. I will be rotating the squad to a certain degree."
