The Danish striker struggled during his time at Villa Park with illness.
The 6 ft 5 ins tall striker was certainly built for the Premier League, but it is fair to say it never really took of for the 23-year-old.
He played just six times for the club, scoring one goal against Sheffield United in an FA Cup tie back in January.
He was indeed more famous for an incident when Tottenham Hotspur defender Jan Vertonghen decided to pull his pants down, literally.
He struggled with a bacterial infection at the club and told The Guardian he even developed a small addiction to his medication.
The Danish international never followed up his 36 goals in 98 games for AaB and returned to the club initially on loan last summer, and permanently in July.
But things have not improved.
He has not scored in 10 appearances for the club this term and he has not been a regular starter, with Lukas Spalvis and Thomas Enevoldsen ahead of him in the pecking order.
The Danish club's sporting director Allan Gaarde told Danish publication Bold this week that they are sticking by the player, despite reports he might want to move away in January.
Helenius was certainly one of the poorer signings in the Paul Lambert era at Aston Villa but hopefully he can start hitting the back of the net soon.
