Lazio coach Maurizio Sarri has admitted frustration with recent results.
Sarri reflected on their 4-0 defeat to Napoli.
"I always want to win games," he said. “However, the difficulties are evident. In the three games after the national break, we scored three points.
“We also scored few points after the Europa League. If you look at normal games, on the other hand, we have a very high average.
“It's not an easy problem in today's football, because unlike in the past, we always play every three days. It's not a tactical problem, but a mental and unconscious problem.
“The nervous system is discharged. On Sunday, we already knew we were going to lose during the warm-up. It was evident. It gave me a sense of frustration."
