Ajax has complained by KNVB director Henk Kesler about Jaap Uilenberg. The referees-boss used Klaas-Jan Huntelaar as an example during a referee meeting. "Huntelaar is a polluter. By his way of jumping, with his elbows up. Every airbattle that he is concerned, he should get yellow. He is doing it deliberately."
If that's going to happen we'll see alot more yellow and red cards next season
