The 26-year-old striker is now two ahead of Manchester United's Robin van Persie with 21 league goals in an outstanding personal campaign, despite the fact that Brendan Rodgers' seventh-placed side have struggled for consistency this season.
"There is not much more you can say about [Suarez] - he is world class and his hat-trick speaks for itself," Allen told the club's official website.

"With Luis, you know he is going to conjure something up at any given moment in a game. To have that in your team is enormous. He's always hungry for the ball and to get more goals - you can't really ask for much more."
Despite courting controversy in the past with an eight-game ban for racially abusing Patrice Evra and facing continuous accusations of diving, Allen feels that lethal finisher Suarez would be a worthy winner of the PFA Player of the Year award given his stunning season.
"Obviously we're biased as Liverpool players and we're going to want to see him win it," the midfielder admitted, "but we'll have to wait and see what unfolds."
The comprehensive demolition of the Latics, as well as the clean sheet, give Allen hope for the future of the club even if they fail to reach a high finish in the Premier League this season.
"It was a fantastic day for us - we were clinical and with a clean sheet as well, you can't really ask for much more," he continued. "It's definitely up there with our best performances this season, especially when you consider it was away from home as well.
"It bodes well for the future. When you score four goals, you can focus on the way we attacked but I think the way we defended shows that side of our game is really solid at the moment."
