The former Red Devils striker has watched on from afar in 2018-19 as those at Old Trafford have endured another forgettable campaign.
Serious questions have been asked of several members of a supposedly star-studded squad, with the likes of Paul Pogba, Alexis Sanchez and Romelu Lukaku coming in for criticism .
United’s all-time leading goalscorer told the Wayne Rooney Podcast of goings on in Manchester and his hopes for the future: “I think the players need to fear someone.
“They need to fear Ole Gunnar. They need to fear Michael Carrick. They need to respect them but fear them also.
“The way the game has gone has changed, society has changed. 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.”
