Sarri believes the winter transfer window doesn't work.
He said, "It's crazy to have a market window of 30 days at this moment of the season. We play every three days, so we need something else.
"The market window in January would be better for one week, 10 days, no more. But the summer window is also crazy, three months.
"I am not involved in the market. I spoke to the club. They know very well my opinion. In my opinion we need two players, and then it depends on the club's decision. I don't know anything about the market day by day, minute by minute."
