Northern Ireland manager Michael O'Neill believes David Healy still has "loads to offer" at both club and international level.
Healy, his country's record scorer with 36 goals, is currently a free agent after he was released by Bury in May and O'Neill omitted the striker from his 20-man squad for the World Cup qualifier against Russia.
The 34-year-old is among three players without a club that O'Neill has opted to leave out of his party for the rearranged Group F game at Windsor Park, along with defender Chris Baird and midfielder Paddy McCourt.
O'Neill says the trio are on standby, and regarding Healy, he said: "David still has loads to offer I believe.
"I think if he finds a manager who has faith in him and gives him the opportunity, he is more than capable of scoring goals for a club and still at international level.
"I think it is very difficult for any of our players who are unattached at the minute, and having spoken to the players themselves, they are in full agreement with that."
O'Neill's side have scored only three goals in their five qualifying matches, drawing three and losing two of those fixtures.
"We have created chances, there is no doubt about that," said O'Neill. "In all three of our home games we have created a lot and we haven't capitalised on that, which is probably the biggest disappointment.
"The opportunity is there for someone like Kyle (Lafferty), Martin (Paterson) or Jamie (Ward).
"Kyle is at a new club in a new country and I think it is something he is looking forward to. Hopefully we see that in his international form."
