That’s after spotting David De Gea “reading his notes” and still not making one single save.
The Red Devils booked their place in June’s Wembley final against rivals Man City with a tight win over Brighton on Sunday.
With the scores tied at 0-0 following 120 breathless minutes, both sides lined up for spot-kicks at the Brighton end.
The two teams each slotted home their first six penalties.
But disaster struck for the Seagulls when Solly March blazed his effort over the bar.
And it fell to Victor Lindelof to slot home the winning penalty to set up a final date against City.
The shootout was marked by neither goalkeeper making a save.
Robert Sanchez came close on several occasions, even getting his hand to one effort.
But De Gea seemed to dive the wrong way almost every time.

The Spaniard constantly paused between efforts as he appeared to read secret notes hidden in his towel.
And United fans couldn’t believe they made it through the shootout against Brighton, especially considering De Gea’s previous records.
Most notable is the 2021 Europa League final defeat to Villarreal where he conceded 11 penalties before missing United’s crucial one himself.
One fan said: “De Gea just watching these penalties like us at home.”
Another declared: “So bad from March, all you have to do against De Gea is put it on target, man is a hologram.”
One noted: “De Gea took notes to a penalty shootout and dived the wrong way for almost all of them.”
Another added: “F*****g hell, we actually won a shootout and De Gea didn’t even need to save one.”
