REDS boss David Flitcroft will be happy with his side once he's brought in one more striker.
Flicker, who's rubbished reports that the Oakwell club are chasing ex-England striker Andy Johnson, is constantly monitoring the transfer market.
"Once we get another striker I think the squad will be well-balanced," he said. "I'll be very comfortable going into the new season with the squad."
The Reds missed out on Michael Higdon, who was the top scorer in the Scottish Premier League last season with Motherwell. Despite the Reds' best efforts, Higdon settled on a move to Dutch outfit NEC Nijmegen.
"We're after a player who can score goals," Flicker said.
He's confident that the Reds have enough defenders now, after last week's signing of Lewin Nyatanga.
"We have got a good balance across the defence. Martin Cranie and Scott Wiseman can play at right-back as well as centre-back.
"We have cover and flexibility whether we have five at the back or even four."
