The standard of refereeing in the Premier League this season "hasn't been good enough", says Burnley manager Vincent Kompany.
Kompany was shown a red card by referee Darren England during the 2-2 draw at Chelsea on Saturday for protesting against a penalty decision which led to defender Lorenz Assignon being sent off.
Six Burnley players have been sent off in 30 games this season, the most of any other Premier League team.
Kompany said he is "not shying away" from giving feedback to officials and does not have "any issues with being fined".
He said: "I've said it to the referees themselves, the officials - refereeing hasn't been good enough this season.
