Chelsea boss Mauricio Pochettino admits he needs to apologise to Harry Pell after Wednesday's Carabao Cup win against AFC Wimbledon.
Pochettino was angry with the way Pell won Wimbledon's penalty, which James Tilley converted to have the visitors ahead on Wednesday night.
He later explained: "I don't know, maybe I made a mistake because I should not talk with the opponent or the players. I was disappointed because we have the tablet on the bench and you can see it's no penalty.
"I was frustrated and I need to say sorry if I say something to the player of Wimbledon because it is not my style.
"That is a moment I was disappointed, I thought it was an unfair decision. Because now in the last few years we have VAR, now we don't have VAR, we are unprotected."
