Ex- defender Paul Parker has joined forces with in targeting for criticism, despite his heroics this season. In February, Keane's went viral, during which he insisted the 30-year-old wasn't a fighter.
"Save us? They're 15th in the league, and he's saving them? Praise the lord," the former United captain replied to Ian Wright on The Overlap. "You have to have a starting point. I go back to it all - talent is not enough. Bruno's a talented player, but talent's not enough."
Parker has relayed Keane's stance during a defence of Ruben Amorim amid questions over whether the United head coach is already under pressure.
The Red Devils are rotting in 14th in the Premier League, with a record-low points tally and a record-high total of defeats.
But Parker believes a major reason for Amorim's early struggles at Old Trafford is the fact that he's got no players he can rely on every week.
The ex-United man has called out Fernandes for his reliability and consistency, even after plundering 19 goals and 18 assists throughout the current campaign.
"I personally don't think Amorim is under pressure. I think he's just going out there, and he's trying to do things," Parker told Express Sport with Betano.
"He can't rest people because people he's resting may need games to prove themselves. And he's got no one really who is reliable.
"People will say Bruno [Fernandes] because of what he's done, but he's not 100 per cent reliable because his game fluctuates as well.
"There's no consistency, no continuity in his game. So I don't think the manager is under pressure."
Parker added that Sir Jim Ratcliffe and INEOS can't afford to sack Amorim in the near future after telling him he must replace Erik ten Hag midway through the season.
He continued: "It's been terrible, the fact that Manchester United, on a few occasions, we've mentioned relegation.
"But again, the people have brought him in... They made him take the job, right? He said he wanted to wait until the start of the season. They didn't give him that opportunity; he's virtually been forced into it.
"But even then, he could have said no, so it's maybe down to him, but they're the ones who brought him into this.
"So they're the ones who should give him every opportunity to get out of it, and then there's no excuses.
"But to go and let him go doesn't make any sense because he's had to go and take over someone else's blueprint. This summer is going to be a big pressure on INEOS. It's a big pressure."
