The Red Devils left it late as they snatched a last-minute goal to beat the Hammers last weekend.
Marcus Rashford scored from close range to hand his side all three points in a much-needed win in the Premier League.
Though it appears the victory came at a price, with damning reports claiming Ronaldo wasn't pleased with Maguire and Greenwood.
The Athletic say that the Portuguese superstar was unhappy with Maguire who failed to pick him out from a clearance.
He told the Man United captain he should have chested the ball to control it instead of heading it away.
Greenwood was also in the firing line, with the 36-year-old frustrated with the youngster's decision to shoot instead of passing to him.
Greenwood’s passing in the final third remains underwhelming and he’s being too selfish at times he doesn’t need to be.The youngster got in a good position But instead of passing to a free Cristiano Ronaldo in the box or Bruno Fernandes outside,he tried a shot that was blocked. pic.twitter.com/NsQiFNp4J3— Red Flash🔴.

What's more, the Man United legend was also angered when Diogo Dalot hit a deep cross that he'd have preferred to come into his feet.
Man United moved above West Ham to fourth place following Rashford's goal.
Speaking after their win, interim boss Ralf Rangnick said he was 'impressed' by the team.
"It couldn’t have been better than that, if you score in the last second of the game. It was amazing," he said. "The atmosphere, the Red Army was pushing the team for 94 minutes.
"A great atmosphere and I can only say congrats and thank you for the support of the fans, that made it a lot easier for us and as I said, an enormous, important win and physically, [it was] a great performance.
"We didn’t always find the right solutions in possession of the ball, especially in the final third of the game, but the way we played defensively after playing only three days ago at Brentford, I was really impressed by the team."
