Gretna are continuing their search for a new goalkeeper.
And Irons indicated that a new number one would be at the club by the end of next week.
As well as a goalkeeper, Irons said the club were searching for at least one defender and a striker.
"We have four players coming in next week and we'll have a real good look at them," he continued.
Gretna have recruited three new faces over the summer, including Uruguayan midfielder Fabian Yantorno.
"Bringing in any player is a gamble," added Irons. "You just hope they settle in.
"The first impressions of Fabian are good. The players have taken to him, he's a good player and he's ambitious.
"He could be a real asset to Gretna Football Club."
