Enzo Maresca said he will assess Chelsea's disciplinary problem in the summer after he has received the most yellow cards this season this season.
The blues have received 96 yellow cards in the Premier League that she places in first place, with the other top five clubs all at least 25 fewer bookings than the men of Maresca.
The red card of Nicolas Jackson for a forearm opposite Sven Botman's face in the 2-0 defeat of Chelsea against Newcastle Last weekend, he earned him an automatic ban on three games.
It means that he will miss the visit of Manchester United on Friday and trip to Nottingham Forest on the last day if Chelsea is struggling for a top five finish to secure Champions League football next season.
Maresca said: 'To Newcastle that was our first red card of the season. If we had a lot of yellow, I don't know I'm honest.
'It is probably also the way we try to be, I intense, aggressive. It is a good question that we probably have to analyze in the summer when we have a day off and to see if there is something that we can do better. '
On Jackson's red card, he added: 'Nico is intelligent enough to acknowledge that there has been a mistake, a mistake.
“For me it's not about age, because regardless of the age you are, if you make a mistake, it's ok because we all make mistakes, but if you make the same mistake again, this is probably not the best.”
