Lazio ultras blamed Claudio Lotito and Maurizio Sarri with two banners placed outside the Formello training ground on Sunday night.
Tension is running high at Lazio following a 3-1 loss against direct rivals Atalanta on Sunday.
Lazio currently sit 9th in the Serie A table, so they are outside a European placement, and ultras seem to have lost patience with the President and coach Sarri.
On Sunday night, two banners aimed at Lotito and Sarri were placed outside the club’s training ground.
One read: “Enrico [Lotito’s son] kick out your father.”
The other one was also against Sarri: “Lotito is an outcast; Sarri is your whipping boy.”
Lazio’s next Serie A game is away at Cagliari. Despite disappointing results in Serie A, the Bianconcelesti have qualified for the Champions League Round of 16 and the Coppa Italia semi-finals.
