Jackson has had a slow start to life at Stamford Bridge, having scored just one goal this season but Pochettino has warned the Senegalese striker to control his aggression after picking up four yellow cards.
"I talked to him today. We had a meeting with him and also Enzo [Fernandez]," Pochettino said, as per Goal.
"For a striker to pick up four yellow cards from talking to the officials, it shouldn't happen. It would be ok for different actions but not for that.
"He is young and he needs to improve, he will be a fantastic player but he needs time. He needs to be calm and relaxed in front of goal and it will arrive. He needs to be clever to not protest to the referees."
"Maybe it's his normal behavior on the pitch or maybe it's because the rules changed this season.
"He has come from Spain and here it is more sensitive this season. Hopefully, he doesn't get another one on Sunday because he will be suspended."
