It would be right to start this by saying 'surprise surprise' in an overly sarcastic tone, however, this genuinely is a surprise. Like actually.
Leroy Sane left David de Gea with a six-egg omelette on his face on Wednesday night after the Spanish goalkeeper failed to deal with what seemed a relatively routine effort from the German.
Instead of simply catching the ball in his midriff, De Gea thought he'd try and save it with a combination of hand and foot. Something he tried and failed miserably at, handing Manchester City a two-goal lead at Old Trafford.
That error obviously sealed the Premier League title for Pep Guardiola's men. Well, that's essentially what this derby was billed as.
As per the world of Twitter, he was naturally lambasted for his efforts, following up from an equally lethargic gaffe against Barcelona at Camp Nou.
Some United fans went full Monty Python on the matter, which goes to show there's always light at the end of the tunnel, no matter how dark, dreary, cold or miserable the tunnel may be.
As was to be expected, Liverpool fans weren't too chuffed with Ole Gunnar Solskjaer's men, having so desperately hoped for the Red Devils to regain an inch of dignity and earn a positive result, De Gea played his part.
It seems none of United, Arsenal or Chelsea fancy Champions League football next season, as the race for the top four...cools down?
Either way, perhaps De Gea will continue putting in error strewn performances in an apparent effort to move to sunnier climates. You never know, but something must be up.
Exit by error, is that a thing? It should be.
