Neil Aspin said he was keen to keep trialist Jamie Jackson after his winning goal against Notts County on Saturday.
Jackson has impressed in his two second-half appearances for Town and struck a superb 20-yard effort to clinch Halifax’s 1-0 win over County at the Shay.
Aspin is pleased with the former Chesterfield forward’s impact so far and hinted Jackson could become a permanent fixture at the club.
He said: “He’s done well. It’s hard for anybody who’s on trial because they’ve got to come and make an immediate impact.
“He was lively the other night and he took his goal well so he’s somebody that we’re keen to keep as part of the squad.
“We don’t have a massive squad and when we had training last Monday we were a little bit thin on the ground because we had three or four injuries and then you’re suddenly looking a bit threadbare.
“We can’t afford to be like that going into the season so we need to add a couple more.
“I don’t want a massive squad but you’re always going to have one player injured in your squad so you’re probably looking to have 18 or 19 players.”
Aspin revealed he has an idea of his starting 11 for the opening game of the season, but that his prefered team is far from set in stone with two pre-season games left to play.
He said: “Lots of people have had an opportunity, we’ve tried lots of different formations.
“We’ve got a couple of games left which we’re going to look at a couple of things.
“I have a team in mind to start the season but there’s always a chance for somebody to change my mind.”
Josh Wilson was again sidelined with injury but could be in contention to play at Mossley on Wednesday.
Aspin admitted the win over Notts County, Town’s third against League One opposition, wasn’t a great spectacle but said his players will benefit from another good work-out.
The Town boss added: “The conditions with the heat and the pitch was like playing on Velcro and I think it affected the game.
“But in terms of getting through a 90 minutes and for the players fitness-wise it was good, but as a spectacle I didn’t really enjoy watching it.”
