Chelsea boss Mauricio Pochettino has revealed that he has held a meeting with Enzo Fernandez and Nicolas Jackson over their frequent bookings this season.
The Blues have struggled in the Premier League so far this season and dropped points once again when they faced Bournemouth last weekend.
Pochettino's side host Aston Villa at Stamford Bridge on Sunday and will be hoping to get a positive result in front of their own fans.
While Jackson looked sharp in the early stages of the season, the Senegal international has become a frustrated figure and picked up four yellow cards in five matches - all for talking back to the officials.
