Kilmarnock manager Kenny Shiels believes trialist Derek Riordan is likely to end up on mainland Europe instead of Rugby Park.
The former Hibernian forward is seeking a new club after leaving Chinese outfit Shaanxi Chan-Ba in November.
"I think Derek is going to Europe," said Shiels. "We don't know.
"I would like to think we're one of the favourites if he comes to Scotland. It's not ruled out, but quite diminished."
Shiels has made a strike partner to Paul Heffernan his priority during the January transfer window but admits that he is finding it difficult to find the required quality at the price the Scottish Premier League club can afford.
BBC Scotland revealed last week that Kilmarnock could face competition from Turkish club Kayserispor for Riordan's signature.
However, a decision does not appear to be imminent by the forward, who has been capped three times by Scotland.
"He hasn't trained this morning, but he'll be back again, hopefully this week," said Shiels before reports emerged suggesting that the player is being given a trial by Blackpool.
Riordan left Hibs in July for the Chinese Super League club but departed Shaanxi Chan-Ba after a disappointing five-month spell.
The Kilmarnock manager is keen to sign Riordan until the end of the season and hopes that the Rugby Park side's passing game would encourage the forward to stay.
"Derek likes our way of playing," he told BBC Scotland last week. "He knows it would suit both parties.
"We would benefit from him and it's an opportunity for him to express what he can do.
"All Derek wants to do is play football, so hopefully something might happen, but it's a bit pie in the sky at the moment.
"He would have the freedom to play and go and express himself. We wouldn't want him to do any defending.
"We'd just play him in an area where he can exploit other team's weaknesses and certainly, with the quality he has, it would be suited to our style of play.
"But there are lots of things that have to be resolved, which I can't go into detail on."
Riordan, who spent two seasons at Celtic between his two periods at Easter Road, has scored 95 Scottish Premier League goals - making him the third highest goalscorer in the history of the competition, behind prolific Old Firm duo Kris Boyd and Henrik Larsson.
