Flitcroft is eager to bring in some new faces, with the Tykes picking up their first point of the season in Saturday's 2-2 draw at home to Charlton in the Championship.
"I'm starting to see movement now," he said. "We've been fishing for a bit now and we'll probably catch someone this week."
Midfielder David Perkins was taken off with a dead leg against the Addicks but Flitcroft is hopeful he will not be sidelined for long.
"He's taken the tackle and it was a big impact," added Flitcroft. "We'll know more when we assess that."
