Former Switzerland Under-19 cap Danijel Subotic is poised to win a contract with St Johnstone - if the club can cut international red tape.
The Croatia-born 22-year-old has impressed on trial and Saints boss Derek McInnes wants to offer a deal.
But the club website stated: "A three-month stint with Universitatea Craiova has muddied the waters in terms of the player's paperwork.
"But hopes are high that this can be resolved so he can be taken on."
However, the Perth club have appealed to the Scottish Football Association and world governing body Fifa to help cut through what they describe as a "red-tape wrangle".
"The club is now pulling out all the stops to make it happen," they state.
Subotic came through the youth ranks at Basel in Switzerland but switched to Portsmouth in 2008.
After a spell on loan to feeder club Zulte Waregem in Belgium, his Pompey contract was terminated by mutual consent so he could join Italian Serie B club Grosseto in 2010.
However, the players who has dual Swiss and Bosnian nationality moved to Romanian Liga 1 club Universitatea in February.
Now he has impressed while on trial alongside Marcus Haber, the Canada international striker who had a loan spell with St Johnstone from West Brom last year.
McInnes released a number of strikers at the end of last season and has already brought in former Falkirk forward Carl Finnigan and Sean Higgins from Dundee.
