Sarri said: "I think it is a mental problem. In the last three matches we had a problem with the approach of the match.
"But not only. We have to be careful and be focused on this problem.
"For sure it is not a physical problem, we have some difficulties. It is not a tactical problem.
"In the last 15 minutes of three matches it was the opposition was more determined than us, we have to approach the match in a different."
Sarri said: "I don’t know the movement of the contract. He is doing very well, he played on Sunday so was with us on Tuesday.
"But I hope we can do [a new contract], I hope so."
