Dunfermline manager Jim McIntyre was left dismayed by defensive mistakes in his side's 3-0 defeat by St Johnstone.
Goalkeeper Chris Smith punched Liam Craig's corner into his own net after 36 minutes to gift Saints the lead and Smith spilled a shot to enable Fran Sandaza to score the second.
"It's hard to take because we've put so much into the game," said McIntyre.
"We need to get some bodies in and hopefully that'll happen in January."
Craig doubled his tally after Sandaza set him up with 30 minutes remaining to leave the Pars rooted to the bottom of the SPL table, level with Hibs on 14 points but with an inferior goal difference.
"I thought for the first half hour our gameplan was good: we were the team in the ascendancy and then we make a mistake for the first goal," said McIntyre.
"And we do the same for goals two and three; I'm sick of the same old story. If we don't stop conceding these goals then we're never going to give ourselves a chance to win games.
"It's clearly more than hard work on the training ground, because we do plenty of that. We need to get some bodies in and hopefully that'll happen in January.
"The board are working extremely hard to raise funds but how much will be made available we're not sure."
McIntyre, however, is remaining upbeat about Dunfermline's hopes of remaining in the top flight this season.
"You've just got to look at Aberdeen," he said. "Three results there took them away from the bottom two, so we'll be looking to do the exact same."
