Sarri said, "Manchester City are in another category. We have to play and to fight to be in the top four. The result is very difficult for this, because I know in every match you have to gain points.
"In the last championship in Italy I lost Serie A with 91 points, so I know very well you have to gain points in every match.
"City are the best team in Europe, maybe the best in the world. They can win the Champions League, but that depends on moments. Last season I think they were the best team in the Champions League, but they played two matches not in the best moment of the season."
