There was an abundance of expectation and excitement every time Ronaldo was on the ball, and he took aim on 10 minutes, though he could only find the side-netting.
Raphael Varane then headed wide from a Luke Shaw corner on 19 minutes.
Not long after, Fernandes audaciously attempted his own Beckham vs Wimbledon moment with an effort that dropped just over the bar.
United struggled to unpick Newcastle's low block, and it appeared like the game would be goalless going into halftime.
That was until the inevitable Cristiano Ronaldo opened his account on his second debut for the reds.
Freddie Woodman spilt Greenwood's shot, and Ronaldo was there to tap the ball into the back of the net from five yards, causing an eruption from the home support and plenty to rue their decision to wander off for a halftime pint before the whistle blew.
Much of the same from the reds to start the second half as they kept up their domination.
However, despite spending the majority of the game behind the ball rather than on it, Newcastle drew level on 56 minutes after a well-worked counterattack.
Ciaran Clark drove the ball out from the back from his own half before passing to Allan Saint-Maximin, who fed the ball into Javier Manquillo to drive home.
The Geordies' delight didn't last long, though, as homecoming King Ronaldo bagged again!
The unstoppable Shaw carried the ball up the pitch and slid through to the Portuguese in the area, and he was never going to miss one-on-one, thumping his shot through Woodman's legs.
David De Gea wasn't the busiest man on the day but did well to be alert on 67 minutes to make a smart save when Joelinton took aim.
Around 10 minutes later, the largely unneeded De Gea played a stunning pass from a dropkick to find Greenwood, who broke forward.
He laid it back to Pogba, who found Fernandes 25 yards out, who picked out the top left of the goal for United's third goal.
A fourth rounded off a dominant day for Solkjaer's side when Anthony Martial dummied Pogba's pass into Lingard, who turned and deftly curled his shot into the goal.
