Brighton pulled off a shock 3-2 win over Manchester United on Sunday afternoon.
The Red Devils found themselves 2-0 down within 27 minutes after quickfire goals from Glenn Murray and Shane Duffy.
Romelu Lukaku quickly pulled one back from close range but Jose Mourinho's side were unable to produce a comeback.
Ivorian defender Eric Bailly gifted the Seagulls a penalty and Pascal Gross beat David De Gea to restore Brighton's two-goal lead on the stroke of half-time.
It was a disastrous day for Man United, despite Paul Pogba pulling one back in stoppage time.
That's because rivals Manchester City thrashed Huddersfield Town 6-1 earlier on Sunday afternoon.
Brighton's third goal
Man United fans - as well as Gary Neville on commentary - rightly criticised Bailly for his rash challenge which handed Brighton a penalty.
"It’s really poor from Bailly, it’s so poor," said Neville on Sky Sport.
"Jose will hate what he’s seeing. All of them [the defenders] dive in, every single one of them. He will be absolutely fuming."
But plenty of United fans on social media were pointing the finger of blame at De Gea.
The Spanish goalkeeper chipped a difficult pass to Fred in Man United's own half and the Brazilian was immediately dispossessed, leading to Bailly's mistake seconds later.
De Gea won Man United's Player of the Season award in May but struggled with Spain at the 2018 World Cup.
He's widely regarded as one of the best goalkeepers in the world - but even he is not spared from criticism.
Before the Brighton defeat, Mourinho had confirmed rumours that De Gea is close to signing a new contract at Old Trafford.
"David is a Manchester United player. He will sign a new contract as soon as possible. He likes it here.
"We love him. We want him to stay. He wants to stay.
"I think it was a collective situation involving the player, the agent and Manchester United. The agent didn’t create a war to try to achieve his objectives.
"He respected the club. He respected the player. The player was always keen to stay and happy to stay."
