Vincent Kompany's thunderbolt for Manchester City against Leicester had felt like the final hammer blow to the Reds' fading hopes in a never-before-seen slugfest of a Premier League title race, meaning a likely 97-point tally would almost certainly not be enough to end that 29-year wait for a 19th league championship.
And the previous week's scarcely-believable three goal defeat, despite outplaying Barcelona for long stages of the Camp Nou first leg, had surely meant a season of remarkable quality and consistency was now almost certain to end in more empty-handed heartbreak.

For the visitors from Catalonia, this was an opportunity to exorcise the ghosts of the previous season's surrender in Rome when they had lost a three-goal home first-leg lead and crashed out in the quarter-finals.
Barcelona' whole season had been predicated on winning the Champions League back after rivals Real Madrid's three successive wins following their last triumph in 2015.
As a player, these are the things you like to experience."
The second leg will be the first time Philippe Coutinho has returned to Anfield since his £142m transfer from Liverpool to Barcelona 16 months earlier.
"Really it is something that has stuck in my memory," he says.
Whether it's 90,000 or 70,000 or whatever, it feels more like a big family than just a club."
Meanwhile by the Albert Dock, we see Barcelona fans arriving, enjoying fish and chips and taking in the city's sights
'Let's go for the sixth' is the cry they greet each other with, the Blaugrauna - like Liverpool - currently having five European Cup wins on the board and hoping to move ahead of their hosts and fellow quintuple holders Bayern Munich into third in the all-time list behind AC Milan and Real Madrid should they prevail on the night and in the Madrid final.
The fans know they are going into the lion's den though, even with a three-goal first leg advantage ."The people will pressurise them.
You have to be alert and learn from your mistakes, don't you?"
Lionel Messi appears on camera to expand: "It was very hard because we relaxed, we were overconfident and we thought we were already in the final and that match shows you what the Champions League is."
Coach Valverde is asked by Catalan radio if it is impossible for what happened in Rome to happen again against Liverpool at Anfield
"In the same way as we have won, we have to concede that our rival can beat us," he admits.
"But seeing this press room full and seeing what the stadium is going to be like tomorrow, I think there'll be little relaxation."
Now it's down to the real business and we see Anfield just over three hours ahead of kick off on match night.
Catalan radio provides the background with the stirring intro, "The day has come.
This is the toughest atmosphere I've seen in years."
His co-commentator remarks: "I've never seen anything like this in my life."
Divock Origi gives Liverpool a seventh-minute lead and, with trepidation, the commentator says: "And Klopp asks the Liverpool fans to cheer even louder!"
Back in Barcelona, the three fans watching on TV groan and say: "This is not going well but there is still a two-goal margin.
"As captain, making that speech at the start of the season saying that we would bring the Champions League home to the fans, I think more than anyone, he was really hurting and very sad."
Barcelona had clinched the La Liga title the weekend before the first leg of the semi-final against Liverpool and, while their Champions League exit clearly cast a shadow over their campaign, they still have a shot at some form of redemption with the final of the Copa del Rey against Valencia still ahead.
We see 'captains' Messi and Pique meeting the press ahead of the clash in Seville and they make it very clear how desperate they are to put the Liverpool defeat behind them and end the campaign on a high.
"We are the only ones responsible for that match," says Messi.
