Allen picked up the Player of the Year and Club Player of the Year awards on Monday night after an impressive 12 months.
As well as performing well for his country, the 22-year-old starred for Swansea City in the Premier League last season to earn a £15million summer switch to Liverpool.
National team manager Coleman has not been surprised by Allen's progress, while he has also praised the player's attitude.
"The last 12 months have been incredible for Joe . He was born to play for a club like Liverpool and excel," said Coleman.
"He's a great character, very humble and never gets carried away."
