Sarri, however, admits he can't be 100 per cent certain.
He stated: "I think so. Of course I'm not sure, but I think so. I think the situation with the players is very good in terms of our relationship but that's not so important. What's important is to play and get good results but my relationship with the players at the moment is good."
On the empty stadium at the final whistle, Sarri insists he was focused on his players.
"I'm worried about the results, not the fans. Of course I can understand the situation and I can understand our fans because the result wasn't good and we are out of the FA Cup, but I'm worried at the moment about our results."
