Drogba has recalled how Isaac set him on the straight and narrow after last season's Champions League blow-up.
He told The Times: "I don't always worry about what people think, but on this occasion it was really important to come out and apologise because of kids watching the games.
"My son was watching with his friends from school and I was embarrassed by my behaviour. The good thing was that Isaac came to me and said, 'It's not right what you did, Dad, you should have had more penalties, but it's not right to do that to referees.'
"I told him never to do what I did. He's 8 and plays for Chelsea Under-9s, but is very different to me. He's really calm."
