Theo Robinson admits he is in the dark as he waits for his Pompey future to be resolved but declared: I want to earn a deal here.
The 26-year-old striker left Doncaster Rovers at the end of last season and is a free agent as he attempts to seal a contract before the start of the new season.
If I get an opportunity with Pompey, then great.Theo Robinson
After being invited to train with Pompey by Blues boss Paul Cook, the Jamaica international netted his first goal for the club in the 3-2 win at Gosport Borough as Conor Chaplin scored the other two.
While the former Derby County man has other offers on the table, he is prepared to play the waiting game in a bid to sign for the Blues.
And after an encouraging display, he insists he will continue to improve with more training and game time.
Robinson said: ‘I’ve come down here to train. If I get an opportunity with Pompey, then great.
‘I don’t know why it’s perceived as a trial.
‘I have come down here to work my socks off and prove that I’m hungry to score goals.
‘I have got other offers but I am holding off at the moment to see what comes up towards the start of the season.
‘If I am playing well and scoring goals, then hopefully I will earn a contract here.
‘I’m not sure what will happen. You do think about being without a club at the start of the season but I was in the same situation two years ago.
‘Doncaster came in for me two weeks into the season so I’m used to all of this.
‘I will just do the right things and hopefully show what I can do until something gets sorted out.
‘It’s about being ready for whoever comes in, if that is Pompey or another club.
‘But I would like it to be here. I love everything about the place.
‘I will have a word sooner or later to see what is going on.
‘There are other opportunities that I can’t really leave too long.’
Robinson scored seven goals for Rovers in League One last term but was a regular in the Championship for Derby County from 2011 to 2013 and has a decent goalscoring pedigree.
But he shrugged off a potential drop into the bottom division with Pompey.
He said: ‘I would have no problems with playing in League Two at all.
‘This team shouldn’t really be in League Two.
‘There is a big fanbase and it’s a big club, the facilities are great and there are a lot of lads that I know here.
‘If I sign here, I would be thinking that we would do well.
‘Hopefully, I can be a part of it but I’m waiting to see what happens.’
Robinson showed his eye for goal with a good finish from a tight angle against Borough and played a key part in Chaplin’s late winner.
He said: ‘It was a good shift and I was pleased to score.
‘We were 2-0 up and should have seen the game out but we got the win.’
