But the City manager felt it could have been a different outcome if decisions from the officials had gone his team's way in both matches.
Bernardo Silva had struck the post and with Liverpool under intense pressure, Leroy Sane scrambled home what City thought was a crucial second. "It would have been different to go in 2-0", Guardiola moaned. I don't know if you're looking for odds, but I had this conversation a couple of weeks ago and I made the point that prior to Christmas, had you asked me if Liverpool can win this competition, I'd have said no.
"I said it was a goal", Guardiola revealed after the game, per ESPN. "That's the key, it's what you have to do against these sorts of teams".
In truth, City lost this tie in the first leg at Anfield, when they put in a awful first-half performance and found themselves three goals down. Fernandinho remonstrated with the referee and had to be pulled away by Guardiola.
"So we needed to start new, and that's what the boys did, that was clear, we all knew that". I was polite, I was correct.
"He's a referee who likes to feel different, he's special".
Although this recent victory has endeared Salah and co to the Reds faithful, winning their club a sixth European Cup will see this side go down in history. "I told the lads to wake up because it was not good enough and I said we were sitting too deep", Lovren said.
City's 3-0 first-leg loss at Anfield left them needing a four-goal turnaround at the Etihad Stadium on Tuesday night.
Gabriel Jesus' early goal hinted at a Manchester City fightback, but it never materialised as they struggled to find that clinical edge in the final third. "Of course that has an influence". "The other teams will have their targets as well when we meet them in the semis; I think they are not without ambitions".
Klopp would have been livid if one of his key players was absent for the first leg of the semi-final because of a celebration.
Liverpool manager Jurgen Klopp hailed the maturity of his side to see out a first-half onslaught.
"The regret is definitely the first six or seven games of the season in the Premier League", added Lovren.
Speaking on BT Sport after the game, Klopp revealed what he said to his players to inspire them to victory after a disappointing first half by their usual standards.
