The West Ham fans asked a pertinent question of Manchester United: "How s**t must you be?" United are so bad they were 17th in the Premier League table at one stage in the first half.
They rose to 16th thanks to Tottenham, predictably beaten by Crystal Palace on their own patch. The Europa League finalists are also battling to outdo each other for the worst team not to be relegated from the top flight. "If you beat Spurs, you're not all c***s," is just about the nicest thing West Ham's away-dayers have ever said to United.
A West Ham staff member said to a colleague at half-time, "If we win, we'll rinse this." West Ham had won four games on the road all season and they have left Old Trafford with three points for the first time since 2007. They had not won in nearly three months. Yet United are winless in the league in two months.
West Ham are above United in the table now. United's numbers are worth outlining in black and white for anyone prepared to cut this United squad any slack: played 36, won 10, drawn nine, lost 17 and with a -11 goal difference. United last lost 17 league games in a single season in 1973-74. Ie. the relegation season. Their goal difference was actually better under Tommy Docherty's doomed squad.
West Ham's followers chided Rasmus Hojlund with a chorus of "F*****g useless". That could have applied to the entire United side. They had signings purchased for £72million, £60m, £58m and £67m in their starting XI. United discovered years ago it is not about quantity but quality.
United could realistically lose half of their 38 league fixtures. Chelsea and Aston Villa, their remaining opponents, are in pressing need of points in the attempt to qualify for the Champions League. The latter is four days after the Europa League final.
Still the United matchgoers refuse to turn, not when there is a cup final on the horizon. The first half ended without any boos. There were none at full-time, either.
The odd matchgoer vented, at Harry Amass deciding against a cross or the lack of pressing from Hojlund. The United denizens mostly stayed silent. That silence spoke volumes.
United's supporters have become so accustomed to defeat they are apathetic. There was barely a murmur of discontent at their bottom-place finish in the Champions League group stage last season. Those feel like heady days now. Their league position is doubly worse than last year's eighth.
The afternoon was compounded by a significant injury. Leny Yoro was able to walk off but his body language was downbeat. He was clutching his left foot when the physio Jordan Reece assessed him.
Amorim immediately replaced Yoro and Luke Shaw, suddenly a genuine contender to start in Bilbao if Yoro does not recover within ten days. Shaw has not completed 90 minutes for his club since February last year.
Despite the sunshine and serenity, Bruno Fernandes was not easy like Sunday morning. He rebuked Kobbie Mainoo for his positioning as early as the 12th minute while Yoro had the ball. Fernandes elaborated on his gripe when the ball went dead.
With Fernandes back in midfield, United effectively accommodated four No.10s. Having been too defensive-minded against Athletic Bilbao, the balance was too extreme in the opposite direction.
Amad, starting for the first time in three months, was effectively pitted against Mohammed Kudus. That was proven to be a mismatch when the Ghanaian held off Amad to drive the ball in for Tomas Soucek, holding off Harry Amass in another mismatch, to cutely flick the ball in.
Amorim fretted over Noussair Mazraoui's fitness on Thursday evening yet he stayed in the starting line-up. Mazraoui at right centre back and Amad on the right wing was possibly a trial for the Europa League final. Amad teed up Fernandes for an early shot, drew the only save from Alphonse Areola in the first half and played Hojlund in. Amad was United's only positive.
Aaron Wan-Bissaka was greeted by Fernandes, Yoro and Victor Lindelof in the tunnel on his return. He was serenaded more often by the travelling Cockneys in five minutes than he was in five years at Old Trafford. He showed why he is serenaded so often with a canny reverse pass for the opening goal.
Wan-Bissaka arguably saved his best performance at Old Trafford for his first visit as an opponent. He pickpocketed Manuel Ugarte and perceptively squared the ball for Jarrod Bowen to tap in for 2-0.
Ugarte has admitted that physicality is the biggest difference between the Europa League and the Premier League. His dawdling on the ball encapsulated this United side in a microcosm. Every weekend, they live up to their 'worst-since-relegated' billing.
West Ham's followers singled out Hojlund and he failed to convert a Harry Maguire knockdown three yards out from goal. David Moyes was in attendance and both of his former teams were better off with him in the dugout.
There were plenty of answers to the West Ham fans' question.
