The Red Devils claimed a share of the spoils at St James’ Park after a disappointing overall performance, paying the price for a poor first-half display as they went into the interval a goal down.
Allan Saint-Maximin wreaked havoc throughout, pulling Raphael Varane out of position and turning inside Harry Maguire to open the scoring with a sublime curling effort.
The Magpies had multiple opportunities to double their advantage only to find David de Gea in the way, with the Spaniard making a string of superb saves.
The pair were spotted complaining about their team-mates when losing possession and throwing their arms up in the air in frustration.
But Rangnick, 63, was more keen to focus on how his side failed to control game rather than highlight the apparent lack of unity in his side.
“I don’t think body language was our biggest problem today,” Rangnick told Sky Sports after the game.
“Our biggest problem was the mistakes we made.
“Even when we scored the equaliser we were not really controlling the game and taking the wrong decisions.
“It’s all about energy, physicality and who wins the second balls. In all those areas we weren’t at our best.
“The good thing is we got a point but the performance needs to be better.”
But Neville, who hit out at Ronaldo and Fernandes for their behaviour on the pitch disagreed with Rangnick’s assessment of the match on Monday night.
The Man United legend blasted Ronaldo for failing to recognise the fans at the final whistle, instead running down the tunnel, while also picking out Fernandes for “whingeing” during the match.
“I said it after the Everton game earlier on in the season when Cristiano walked off and I thought it put pressure on Ole Gunnar Solskjaer. He’s run off again tonight,” Neville said on Sky Sports’ Monday Night Football.
“He ran off at Watford when the manager was going to get sacked and everyone knew he was going to get sacked… and at Norwich.
“[Ronaldo and] Bruno, those are the two senior players in that dressing room. It’s devastating for the young players if the two best players in the team are looking at the others as if they’re not good enough.
“Cavani takes that away because I don’t think he wilts in the presence of Ronaldo or a Fernandes.
“He stands up to them and helps the other younger players on the pitch. He needs to be on the pitch.
“They need to rid of that whingey attitude, they really do. You’ve got to go and clap the fans at the end of the game.
“I don’t care how you’ve played, I don’t care what the result is, get over to them fans and clap them.
“You have to do that, particularly when you’re the best player in the world and one of the best of all time.”
