Enzo Maresca said he will review Chelsea’s disciplinary problem in the summer after being awarded the most yellow cards so far this season.
The Blues have received 96 yellow cards in the Premier League which puts them in top spot, with the other top five clubs all on at least 25 fewer bookings than Maresca’s men.
Nicolas Jackson’s red card for a forearm to the face of Sven Botman in Chelsea’s 2-0 defeat to Newcastle last weekend earned him an automatic three-game ban.
It means he will miss the visit of Manchester United on Friday and trip to Nottingham Forest on the final day as Chelsea wrestle for a top-five finish to secure Champions League football next season.
