Lazio coach Maurizio Sarri was left frustrated after their defeat to Salernitana.

Salernitana stunned Lazio at the Olimpico 3-1 on Sunday.

Sarri said: “We had the game completely in hand until the equaliser, which caught us unprepared. We probably assumed the game was won and that made us lose all our balance and shape," Sarri told DAZN.

“The game changed after it went to 1-1, the referee did not help keep the situation calm, but we still should've had the strength to overcome all of that."

Sergej Milinkovic-Savic received a yellow card, which infuriated Sarri.

“Not only was it not a yellow card, it wasn't even a foul," said the coach. “Milinkovic-Savic had already passed the ball, the other player was late and there was no way to avoid the collision.

“In 50 years of football I have never seen this type of yellow card given for a team that is attacking and in possession. If I say what I really think, they will give me a six-month ban."

He added: “We need to get ourselves back in order and start again, beginning with the trip to Holland, then we can think about the derby after that."
