"Obviously we've got two of our main goalscorers out, but it also presents an opportunity for some of the other lads to come in, make a name for themselves and make themselves heroes", said Alexander-Arnold.
It was always going to be tough for Liverpool after they were handed a 3-0 drubbing by Barcelona.
He would leave for Barcelona 2014 shortly after his 31 goals nearly saw Liverpool win the Premier League.
For only the fourth time in the competition's history a team was eliminated from a knockout tie having won the first leg by three or more goals - the last occasion being Barca against Roma in last season's quarter-final.
Liverpool fans loved Klopp's reaction.
However, two goals apiece from Divock Origi and Gini Wijnaldum - only on as a half-time substitute for the injured Andrew Robertson - sent Liverpool into the final for the second season in a row.
"When you have a collapse of this nature", Barcelona coach Ernesto Valverde said, "we will have a few disgusting days ahead".
Suarez will be joined by Messi and Philippe Coutinho on his return to Liverpool after a £142 million ($186 million) move to Barca a year ago.
"Once they scored and they pressed us high it was very hard".
Some statement from a player who played over 500 times for the Reds and was there in 2005 in Istanbul for that famous Champions League comeback.
Liverpool needed an early goal to increase the already vibrant atmosphere and Origi obliged when he struck in only the seventh minute.
It was a moment that left many football fans speechless. In one incident, the striker flicked his boot back into the right knee of Robertson as they ran along together.
Wijnaldum, who replaced Robertson, made an nearly instant impact, making it 2-0 by sweeping home a low cross from Alexander-Arnold.
It was mayhem inside Anfield, the scene of so many of these famous fightbacks.
Prior to kick-off, Liverpool legend Robbie Fowler made it very clear that he was not the biggest fan of the Uruguayan. Origi scored and Barcelona had no answer. Real Madrid went on to win 3-1. Ajax leads 1-0 from the first leg.
