United took two points from their last five Premier League games as their season ended on a face-wrenchingly sour note.
The side’s form drastically derailed after their momentous night in Paris when Solskjaer masterminded a 3-1 victory over PSG to make the Champions League quarter-finals.
After that night, which culminated three months of stellar performance, United then won two of their next 12 games, drawing two and losing eight.
The players’ attitudes have been heavily criticised amid the bad run and Solskjaer has openly admitted a cull is looming.
The Norwegian manager seemingly lost grip of his squad through their torrid run, blaming his players’ poor work-ethic.
But the greatest goalscorer in United’s history, Rooney, believes Solskjaer is lacking a key managerial ingredient, which may have led to the squad’s mercuriality.
“I think the players need to fear someone,” the DC United captain said on The Wayne Rooney Podcast.
“They need to fear Ole Gunnar. They need to fear [assistant coach] Michael Carrick. They need to respect them but fear them also.”
Rooney, who had his run-ins with legendary United manager Sir Alex Ferguson, then went on to criticise members of the squad whose moods are seemingly not dependant on results.
“The way the game has gone has changed, society has changed,” the 33-year-old explained.
“You have got social media. You have got players losing a game and posting something on social media about their new clothing range, their new aftershave, whatever they’re bringing out, which I find remarkable.”
Paul Pogba infamously posted a picture of him pulling an animated, suggestive face shortly after Jose Mourinho was sacked.
“Caption this! @manutd #manutd #mufc @adidasfootball #heretocreate,” read the post.
The World Cup winner claimed it was mistakenly posted by his entourage as part of an Adidas marketing campaign and hastily deleted the photo.
Rooney may have been alluding to that example when saying: “When fans speak up on it (social media) and say ‘why are you posting that?’ they always have the marketing people to blame. [But they should] take responsibility.
“They work for you. Those marketing people work for you. I have people who do similar stuff for me and they never do anything without my instructions.
“If that is what you’re doing, you’re sitting at the top of that business. You have to take responsibility for them.
“These players almost always like to find someone to hide behind, whether that is on their social media or on the football pitch and that’s what they are doing.”
