Liverpool fullback Trent Alexander-Arnold says they must be careful facing Napoli captain Lorenzo Insigne.
It was Insigne's late goal that consigned Liverpool to defeat on their last visit to the Stadio San Paolo, where they will contest their first Champions League away game of the new season for the second campaign running on Tuesday.
Only a commendable team effort prevented the Italian from having a similar influence on the return fixture at Anfield, which the Reds won 1-0 to progress to the knockout stages at the expense of their visitors.
He's a great player, probably a little bit underrated in terms of the respect and the plaudits that he gets, but he's a real fantastic player," the young Scouser said.
I think his teammates will say the same and the people that come up against him will say how tricky he is to actually nullify. He's a good player, they've got many a good player and we need to be ready for that.
He's someone who really helps them play football, understands the way that they want to play, really encourages the team to play out, [and they are] able to hit him and he'll be able to hold the ball up.
He's a really tricky player, really strong, fast, quite agile. He's kind of like Eden Hazard I'd say, that type of player who is tricky to get hold of and mark.
Coming up against him is always a tough test but they're the things that you expect in the Champions League."
