The two forwards' goals might have fired the club to within four points of retaining their Premier League title but as the Daily Express put it their "public shows of petulance and dissent" marred United's 2-0 win.
So what happened? Well, after telling the papers he felt unloved at United and saying he was leaving in the summer Tevez scored a wonder-goal then, rather than celebrating with his team-mates, chose instead run half the pitch, cup his hands to his ears and stare-out the United directors box.
Ronaldo then threw his toys out if his pram when Sir Alex Ferguson subbed him early in the second half. The Portuguese threw a training jacket to the floor in a fit of pique then refused to sit in the dugout and stood to watch the rest of the game in a pouty mood.
The Sun said Ronaldo "blew his top", while a calmer Daily Telegraph reported his actions as an "angry reaction". Either way The Independent claim the actions of the two "provided more pointers to a summer of departures from Old Trafford", and maybe they have a point.
To that end The Times report that Manchester City manager Mark Hughes has refused to rule out signing the Argentine while the Sun claim Tottenham are keen to give Tevez a new home.
Sunday's other Premier League game saw Chelsea put a hapless Arsenal to the sword, beating their cross-London rivals 4-1.
In Monday's Mirror Arsene Wenger blasted his team's defending, and well he might: it was Arsenal's worst home league defeat in 32 years. But seeking to deflect attention away from a poor display Wenger, in the Guardian , accused Didier Drogba of diving. Not the most original accusation ever levelled at the Ivorian and not enough to take the attention off Arsenal's frailty.
Monday evening sees one of the biggest games of the season, and not just because it's a local derby. Newcastle vs Middelsbrough is almost a play-off to see who gets relegated, a draw is useless to either side, while defeat could see the writing on the wall.
Such is the significance of the game that Toon boss Alan Shearer admits in the Sun that it is the biggest of his career.
Just when Newcastle need unity and stability it has deserted them. Take defender Fabio Coloccini.
The Daily Star say he will be dropped from the Boro showdown after speaking out against the club's current situation saying that club he joined in the summer is not exactly as it was advertised to him: "I was sold a club that would be challenging in the top half of the table with maybe a good chance of doing well in the cups."
At the other end of the Newcastle side there is speculation over mis-firing striker Michael Owen. The latest news in the Daily Record sees Celtic rubbish reports that they want to sign striker Owen on a pay-as-you-play deal.
It's as far removed from ideal preparation as possible for Newcastle who are teetering on the brink.
