Lazio President Claudio Lotito urged his men to “not get demoralised” after two consecutive defeats.
“The Coach believed firmly in the potential of this squad,” he said following losses to Genoa and Napoli.
“We must not get demoralised now, just as we did not get over-excited after winning the first three games.
“We have a quality said and must remain humble and united.”
Vladimir Petkovic had been hailed a genius by the Italian media after starting his debut Serie A season with a 100 per cent record after three rounds.
It was Lazio’s best start since 1975 under the legendary Tommaso Maestrelli, but this was followed by a 1-0 home defeat to Genoa and last night’s 3-0 mauling by Napoli.
