Manchester City kept themselves ahead in the race for the title by making light work of their local rivals at Old Trafford.
Goals from Bernardo Silva and Leroy Sane gave the away side a comfortable 2-0 win, which led to a wealth of criticism from commentators and United fans alike.
One man who was not impressed with what he saw from Ole Gunnar Solskjaer’s side was Keane, who was in the Sky Sports studio alongside Gary Neville, Graeme Souness, Joe Hart and Shaun Goater.
The ex-United skipper is known for his no-nonsense approach – and he took shots at everything from the performance of the team to Paul Pogba’s dismal showing.
Keane has been a long-term critic of the Frenchman, despite his purple patch earlier in the season.
And despite lending a slight bit of praise to Pogba, calling him a ‘talented boy’, it was mainly negatives from the Nottingham Forest No 2 last night.
“I wouldn’t believe a word he says. There is no meaning behind it. I don’t even think he believed what he was saying there,” he said after watching Pogba give an interview.
“He’s on about being a team-mate, if you’re going to be a good team-mate you’ve got to run back when you’re defending. It all got a bit heated after the game against Everton, I heard they were throwing their hair-gel at each other. It got that heated.
“The guy is a talented boy, but we’re saying the same thing over and over again. The number of times we’ve seen him in games where he is not sprinting or running back.
“He’s talking about body language – but throws his hands up in the air. He’s a big problem for United.”
Much has been made of Jose Mourinho’s magnanimous Old Trafford exit back in December.
But was it the Portuguese coach’s fault? Or did the players contribute heavily to his downfall?
Keane believes that United’s key players threw Mourinho ‘under the bus’ during his third season in charge.
And the Irishman thinks they will do the same to Solskjaer given time.
“I’m always intrigued when you hear them say they’re up for the next game,” he said.
“I don’t fall for this carry on. Leopards never change their spots.
“These are the same players who threw Jose Mourinho under the bus and they will throw Ole under the bus too.
“There’s too many bluffers at this club to get them back to the very top. Standards have dropped all over the pitch.”
Last night’s performance
Keane wasn’t finished there either, laying into United’s lacklustre display.
And his thoughts saw him clash with fellow pundit and former team-mate Neville.
“Look Gary, they’re strolling across!” Keane snapped at the former right-back when discussing the United’s work-rate.
“Fred sells himself short here. He gives the ball away, which can happen, then compounds it.
“You do not let (Raheem) Sterling then get goal side of you. Why aren’t people trying to stop the shot?
“If that’s a player giving it their all, then Manchester United are in even more trouble than I think, and I think they’re in huge trouble.”
