Trent: You can't be scared to look silly against Messi

"Messi is probably the best in the world. It will be a really tough battle but we kept him quiet for 88 minutes in that game but he still did something special. It shows you have to be concentrated against him for the full 90. You can't be scared to look silly against him", Alexander-Arnold insisted.

The 20 year-old full-back also suggested that Liverpool's approach will be key to the match's outcome: "As a team we have to go out there and be fearless and not hold back. That's the only way we are going to get a result. If we get caught up in fearing their players then that's not really going to work".

Liverpool will be without two key attackers in Roberto Firmino and Mo Salah, but the Englishman insisted the team can rally around their absences: "It won't feel that strange not having Mo in front of me tomorrow. We train with different line-ups, it's not like I'm not used to not playing with him. I'm sure whoever comes in will have an understanding with the other players. It's about versatility and squad depth".

Alexander-Arnold also touched on his feelings following the first leg in Barcelona, which the Reds dominated for large parts but still came away on the wrong end of a 3-0 defeat. "We're massively disappointed with the result but as a performance it was one of our best of the season. It was a strange one. We haven't had many results like that this season. I'm sure Barcelona will come here with respect for us. Not many teams go to Camp Nou and dominate."

 "Both league and Champions League have been a success really, we haven't lost in the league here. PSG was special, Napoli was in its own right. Everyone pushed together as a whole club. We've had setbacks in the CL this season but we have that special bond with this competition." suggested the full-back.

Finally, he spoke about the threat posed by ex-teammate Philippe Coutinho: "He is a really quick player who can go both sides, it's important not to give those type of players too much space and respect. It'll be important to suffocate their players and get the ball back off them as high as possible."
