Inter Milan coach Claudio Ranieri is concerned about the number of penalties being given against his side.
Inter have conceded five spot kicks in only eight games this season, with the latest prompting chief executive Ernesto Paolillo to say Italy's governing body should impose more checks on referees.
Ranieri says, "With this average at the end of the season we would have conceded 25 and so the trend has to change. In past seasons only Parma and Roma have conceded the same number of penalties in eight matches. I'm sure referees will be more careful."
Inter again conceded a last-minute penalty on Wednesday against Atalanta, but it was saved by goalkeeper Luca Castellazzi, to keep the score at 1-1.
Inter face Serie A leaders Juventus in the Derby d'Italia on Saturday.
