Jamie Ashdown is poised to complete a return to Portsmouth, with Steve Cotterill impressed by the keeper.
The 29-year-old was released by Pompey at the end of last season, following six years as an understudy at Fratton Park.
He is, however, back with the club on a trial basis and is closing in on a permanent contract.
With Portsmouth having opted against offering an extension to England international David James, the club have been left short in the keeping department.
Cotterill is aware of the need to address that issue as soon as possible and admits Ashdown is a leading contender.
He told The News: "Jamie has probably shown a good attitude for the past six years here, so let's wait and see how we go with that one.
"The reason I wanted to bring him away (to America) is I wanted him to finish his rehab with us so we would know the nature of his injury.
"We are slowly building him up with a view to him playing in the DC (United) game and maybe a game or two when we get back. Then we can make a judgement on that.
"He's been superb. He is a great lad, he's spent a long time being a number two here.
"He's not the only one in the mix, mind. There are a couple of others I've got my eye on as well."
Cotterill has also explained his reasons for withdrawing a contract offer to James.
He added: "We needed to move on. Everybody knows I am a big admirer of David James, but I needed an answer last week.
"We need a goalkeeper, full stop. David had a few other things he was looking at and we needed to move on.
"I sat down with him twice and wanted him to sign. I couldn't do any more than I did as regards that situation.
"I felt we were more than generous with the time, but obviously he had other options to look at.
"But it's no problem, he goes with my best wishes, there's no problem there."
