The Danish striker has spent this season on loan at Aalborg following a torrid 2013-14 campaign with Villa.
Helenius, 23, sealed a £1.2 million move to Villa from childhood club Aalborg BK in June 2013, having netted an impressive 30 goals in 65 Danish Superliga games over the previous two seasons.
However, the two-time international would go on to endure a torrid campaign with the Midlands outfit, making just six substitute appearances for a total of 153 minutes, while scoring once in the shock 2-1 FA Cup defeat to Sheffield United.
Deemed surplus to requirements in the summer before returning to Aalborg on a season-long loan, the towering front man revealed in an interview with tv3Sport in September that he had contracted a bacterial infection during his time at Villa Park which left him in constant pain, addicted to sleeping pills, depressed and even fearing death.
He has since been making slow progress in his bid to recapture his past form but looks to have made a major breakthrough in recent weeks, bagging a first-half hat-trick in Friday’s 5-0 win over Hobro IK to make it five goals in only three games.
With his Villa deal not set to expire until 2016, some might have wondered whether new boss Tim Sherwood could hand the in-form forward a chance to revive his Premier League career, but agent Mads Bach Lund has now put paid to those hopes.
Speaking to the national newspaper, Lund said: “We have had an ongoing dialogue with Aston Villa the last three weeks and they have made it clear that they do not expect Nicklas back after the summer.
“Therefore, they have also informed us here in the spring to find a new club. But we do not hurry.”
Aalborg would be open to re-signing Helenius, who has now hit 12 goals in 41 games so far this season, but Lund stresses that he and his client are still assessing their options ahead of the summer transfer rush.
“He is not in a marriage with AaB,” added Lund. “We must look at the total package - what the best is for Nicklas. If AaB are interested in keeping him, we look at the options.
“But it may well also be another club. AaB is not in front of the queue compared to other clubs.”
After arriving at Villa with a great deal of promise, before never getting a real shot to prove his worth under the since-departed Paul Lambert, it’s somewhat disappointing to hear that the club will not be giving Helenius a second chance.
At 23 and with his health problems behind him, he could have been an intriguing candidate to backup star man Christian Benteke, or even serve as his future replacement, but it looks like his time with the claret and blues is now over for good.
