The Reds knew they had to better City's result against Aston Villa to have any chance of being crowned champions.
Villa were 2-0 up heading into the final 15 minutes, but Pep Guardiola's side mounted a sensational comeback to win 3-2.
It made Liverpool's 3-1 triumph over Wolves irrelevant, but those inside the away end at Anfield couldn't have cared less.
Rumours spread across the stadium that Villa had equalised late on and Mohamed Salah had to be told City were still in the lead.
Klopp discussed the trolling in his post-match press conference and when asked if it gave him a sliver of hope, he replied: "Yeah, yeah, yeah...
"I don't understand how the Wolverhampton supporters can celebrate when City score a goal. I don't understand these kind of feelings.
"But it was not completely unexpected, we knew it could happen."
Liverpool were still on for a quadruple heading into Sunday, having already won the Carabao Cup and FA Cup in addition to being in the Champions League final.
They were never top at any point as they didn't go ahead until City were already 3-2 up, but Klopp admitted it's the hope that kills you.
He said he'd have rather City blown their opponents away than win the game the way they did.
The 54-year-old continued: "I didn't know 100 per cent what was going on.
"I realised Aston Villa were in front...
"Congratulations, first and foremost, to Man City, Pep Guardiola, all his staff and everybody from City for winning a tough race.
"That's how it is. If you want to win big, you have to be ready to lose big. We lost big today - not the game, but the league.
"The mood is obviously very, very disappointed... I would prefer if City were 5-0 up after 10 minutes.
"When it's this up and down, it was 3-2 and for a second somebody said it was 3-3...
"I felt for a second like we could become champions."
Liverpool will be hoping to end their season an a high with victory over Real Madrid in Saint-Denis on Saturday.
They'll be looking for revenge in a repeat of 2018's Champions League final, which they lost 3-1.
