The £98million striker was dropped by manager Thomas Tuchel for Chelsea’s 2-2 draw with Liverpool on Sunday after voicing his frustration at the club in an interview which was released earlier in the week.
Lukaku, who rejoined the club from Inter Milan last summer, said he was “not happy” with the role he has been playing of late and added he would like to return to the Italian club in the future.
Souness, the former Rangers, Liverpool and Newcastle manager, thinks Tuchel made the right call.
The Scot, working as a pundit for Sky Sports, said: “We’re trying to understand how a player could get his head where it has been to come out with such a ridiculous and damaging statement.
“I think he has come back (from injury), he’s not gone straight into the team, (there is) enormous disappointment attached to that and he has come out with the nonsense he has come out with, which is totally disrespectful.
“He’s 29 years old (actually 28), he’s not 19. He should have known better that this statement damages the football club enormously.
“It is like walking into the dressing room and saying to the other 25 guys, ‘I don’t want to be with you anymore’. I know what I’d be like, ‘if you don’t fancy it here, there’s the… door, and on you go.
“He has got to hold his hand up and say it wasn’t the right place, ‘I made a mistake, I apologise unreservedly’.
“He has lit a fire, a fire that only he can put out. The solution has to come from him. He can’t be expected to be welcomed back into the fold if he is unrepentant.
“He has got to find a way of saying, ‘Sorry I’ve got it wrong’.”
Jimmy Floyd Hasselbaink, the former Chelsea forward, feels the issues can be ironed out.
The Dutchman said: “I think there has to be a way back because he is an asset at the club. They have spent money and I don’t see somebody now giving that same money back.
“It is an investment and you have to find a way back with Lukaku, but he has to understand these are the terms, this is the way forward.
“Yes, you have come in as the main striker but you have to show you are the main striker and be in line with all the others who are part of the team.”
