Michael Appleton has dismissed reports Darjan Curanovic is to sign for Pompey.
Instead the 26-year-old keeper is to arrive at Fratton Park for a trial as the Blues run the rule over him before deciding whether to pursue their interest.
Curanovic was quoted in Slovenian daily newspaper Ekipa saying he would be arriving on July 14 before heading off to Spain for the pre-season tour.
A former Slovenian under-21 international, he is a free agent after playing for Triglav back in his homeland.
Pompey have not got a goalkeeper on their books and the 6ft 3in keeper has shown enough to win the opportunity to impress.
Yet Appleton has stressed a permanent deal has yet to be decided.
Pompey’s manager said: ‘It is true Curanovic is coming over here.
‘But it is for a trial.
‘We have not signed him, it is wrong to say that.’
Jamie Ashdown was not offered a new deal this summer, while Stephen Henderson was sold to West Ham.
In addition, Academy keeper Matt Gledhill has been released, ensuring there is no keeper signed up for the forthcoming season.
With all players back for the start of training on Monday, it is an area Appleton is desperate to recruit in.
He has already lined-up a Premier League stopper to take on loan for the length of the season.
Meanwhile, Curanovic is relishing the chance to come to England for the pre-season.
Speaking to Ekipa, Curanovic said: ‘My dreams came true.
‘I’m heading to England on 14th July and two days later I will travel with my new team-mates to Spain.
‘I just can’t hide my happiness.’
