On Monday night, Alexander-Arnold supplied the assist for Mane's winning goal in the 3-2 victory over West Ham United.
After the England international took his tally for the campaign to 14 goal contributions, Mane was quick to pay credit to the 21-year-old.
The winger told Sky Sports News: "He's a really good player to be honest. Especially for the front three. He's always giving us more assists than we give each other.
"He's a good lad as well. He's working hard all the time and he's listening. He wants more and he wants to progress."
Liverpool are now four wins away from securing the Premier League title.
