Solskjaer was responding to claims from Liverpool boss Klopp that United get more penalties than his team do.
Klopp, whose side crashed to a shock 1-0 defeat at Southampton on Monday night, has highlighted the fact United have had more penalties in two years than his champions have had in five.
Spurs boss Mourinho has also taken a swipe at the number of spot kicks United get, while Blues rival Lampard claimed before last season's FA Cup semi final that Solskjaer's men got more VAR decisions in their favour.
Since Solskjaer took charge of United in 2018 his side have won 42 penalties in all competitions, compared t0 19 for the Reds.
But Solskjaer believes the complaining is a ploy by Klopp and the rest to gain an advantage with referees and he said: "That's a fact, probably, that we have got more than him.
"I don't know how many penalties they've had. I don't count how many penalties they have, so if they want to spend time worrying about when we get fouled in the box fine, but I don't spend time on that.
"I can't talk on behalf of other managers and why they say things like this.
"Obviously I felt it worked last year in the semi in the FA Cup, because Frank spoke about it and we had a nailed on penalty that we should have had that we didn't get - so maybe it's a way of influencing referees.
"I don't know, but I don't worry about that. When they foul our players it's a penalty. It's just when it's inside the box!"
