United fell to a 3-1 defeat in this evening's FA Cup semi-final and de Gea found himself in the spotlight for all the wrong reasons.
He spilled a long range effort from Mason Mount early in the second half that made the scores 2-0 and left United with a mountain to climb.
The mistakes creeping into his game will likely come as no shock to Red Devils legend Keane, who remarked during United's 1-1 draw with Tottenham Hotspur last month: "I'm staggered at [Harry] Maguire and I'm sick to death of this goalkeeper.
"I am disgusted with it. Maguire? de Gea? Hang your heads in shame."
"I'd be swinging punches at that guy."

"I would be fighting him at half-time, I would be swinging punches at that guy. I am flabbergasted.
"Maguire and de Gea, I wouldn't even let them on the bus after the match. Get a taxi back to Manchester.
"These are established international players. Do your job. We're not on about winning league, just getting into the top four! Shocking. I am disgusted.
"Maguire and de Gea should hang their heads in shame. de Gea is the most overrated goalkeeper I've seen in a long, long time.
"That's not even going in the top corner. This is middle of the goal.
"That is not a great save, that's his job, middle of the goal, good height for him. He should be catching that. That's not even that high its middle of the goal."
Manager Ole Gunnar Solskjaer has been a strong defender of his number one and played down Keane's comments.
"Roy was a fantastic midfielder, a good friend of mine, but I'm not sure he would have stopped [Steven Bergwijn's shot] either," Solskjaer joked per Goal.
"David is disappointed with it but the ball is moving through the air. He also had a good save five minutes after, when we had a bad spell and they looked like they could get a second."
De Gea's misery began against Chelsea when Olivier Giroud put Frank Lampard's side ahead just before half time.
His flick caught de Gea off guard which fizzed away from his grasp.
What followed was Mount's strike after Chelsea pressed United high up the pitch.

De Gea kept United in the game with string of saves before Harry Maguire's own goal ended all hopes of a comeback.
Bruno Fernandes scored a consolation from the penalty spot five minutes from time.
