Craig Brown says David Clarkson is too similar to Aberdeen's present strikers to ignite his interest in the 26-year-old released by Bristol City.
The former Motherwell striker, capped twice by Scotland, was released by Derek McInnes' club along with compatriot Jamie McAllister.
"We've got a couple of big guys up there," said Brown while admitting his admiration for Clarkson.
"We don't want to overload with guys of similar build and technique."
Brown, who has released long-serving Darren Mackie, said he was instead looking for "a striker that goes in behind, that's quick and can beat a man comfortably".
Clarkson joined the Robins in June 2009 for reported fee of around £800,000.
But he has struggled to command a regular first-team place with the Championship and was farmed out to League One side Brentford before being ruled out for the rest of the season in January with a fractured ankle picked up on his return to City.
Having steered the Robins clear of relegation, McInnes, who took charge in October after leaving St Johnstone, handed a new contract to former Celtic and Motherwell midfielder Stephen Pearson, who signed in January after a loan spell from Derby County.
However, McInnes released eight players after Saturday's final round of fixtures.
Among them is 34-year-old former Queen of the South, Aberdeen, Livingston and Hearts defender McAllister, who joined City in 2006 and spent part of this season on loan to Preston North End.
Despite McAllister's Dons links, it is Clarkson's release that immediately led to media questions directed at Brown.
"I am interested in every good player," said the Dons manager. "He is a very good player and a smashing guy.
"I know him from the past and I would suggest to you to he is quite similar to the guys we've got."
It is believed that former Scotland Under-21 defender Zander Diamond, who left Pittodrie last summer, has been released by Oldham Athletic despite having been made captain by manager Paul Dickov.
The Dons in January signed veteran Scotland international Russell Anderson after his release by Derby but have released fellow central defenders Rory McArdle and Youl Mawene.
Mark Reynolds is poised to return to Sheffield Wednesday at the end of his loan, while the versatile Kari Arnason has rejected the offer of a new contract.
