That moment, more than any other, summed up a semifinal that veered between mesmerizing and madcap, that even Jürgen Klopp, Liverpool's manager, called "crazy".
"We never do it the easy way unfortunately", Liverpool captain Jordan Henderson said.
Klopp described the game as "wild", adding: "It was a little bit exciting - more exciting than I actually wanted".
A James Milner own-goal six minutes later levelled proceedings before Georginio Wijnaldum restored the Reds advantage on 25 minutes. Real Madrid needed luck too.
Edin Dzeko equalized for Roma early in the second half and Radja Nainggolan scored two late goals for the hosts as the Giallorossi narrowly missed out on another miracle after their stunning 3-0 second-leg victory over Barcelona in the quarterfinals. "If they go one step further this could be the start of something special under this manager".
Merseyside Police, who coordinated safety arrangements with their Italian counterparts, both clubs and match organisers UEFA, have thanked Liverpool fans for heeding security advice.
"Madrid are better than what they have been in the semi-finals, but you look over recent matches in the league and they have been very fortunate in a lot of games".
It has not affected them in the Champions League, however, a competition in which they had been unbeaten this season until Wednesday.
"They're a fantastic team, but we're going to go there with confidence and just give everything". This is a team that can win 5-2 and feel like it has been beaten, and a team that can lose 4-2 and feel like it has triumphed, all in the space of eight days. We have the players.
Around two dozen supporters without tickets sang loudly in bars in the centre of the Italian capital, while those in the Stadio Olimpico showed their appreciation for the players who made it possible. "Told you we do it the hard way always". I forgot the score!
Dzeko's touch let him down and he arrowed a shot wide at the near post following Daniele De Rossi's cleverly disguised 66th-minute pass, while Alisson stuck out a boot to deny his compatriot Firmino on a Liverpool attack that suggested the storm had passed.
