Lazio president Claudio Lotito says he won't move for another coach until he has an answer from Delio Rossi about staying on next season.
"I haven't yet considered the possibility of bringing in a new Coach," Lotito insisted on Radio Kiss Kiss.
"Rossi is a great professional and we want to work out whether his requests are workable in a realistic timeframe.
"Before I start looking at any other tacticians I have to get a definite answer regarding Rossi.
"I'm hoping that we will come to arrangement, but if not I will look elsewhere.
"It's not that I don't want to comment on (Walter) Zenga," he continued. "But there are lots of Coaches and each has their own advantage. We must find someone who can develop our potential.
"Whatever happens, next year I hope to see a more compact, stronger, pugnacious, determined Lazio."
