James Milner urged Liverpool to bounce back as they continue their Premier League title challenge against Newcastle United on Saturday.
Jurgen Klopp's men were made to pay for missed chances by Barcelona, who claimed a 3-0 win in the first leg of their Champions League semi-final.
With two games remaining in the league, Liverpool are already on 91 points – but they trail Manchester City by one and are facing the possibility of a trophy-less season.
Milner called for his side to respond quickly to their loss at Camp Nou, as they prepare for a trip to Newcastle.
"We have to bounce back quickly with a big game at the weekend. Hopefully we can get a good result there and get a bit of positivity going into next week," he told UK newspapers.
"We've seen the character in this squad on more than one occasion over the last few years.
"We all know the character that is there, we need to be together and bounce back. I have no doubt this team will do that."
