Norwich City boss Paul Lambert is unsure if he can continue the club's trend of unearthing talent from the lower leagues.
The Canaries sit ninth in the table despite the squad's relative lack of Premier League experience.
"The lads we've got at the minute came from the lower leagues and the Championship, as everybody knows," Lambert told BBC Radio Norfolk.
"I'm just not sure how many are left out there to go and find."
Summer signings Steve Morison, Anthony Pilkington, Elliott Bennett and Bradley Johnson arrived at Carrow Road without a single top-flight game between them, but have all featured prominently in Norwich's impressive campaign.
And Lambert has not ruled out adding experience to his line-up in order to bolster their bid for survival.
"You're never going to dismiss anything. But the group need a hand and this is a huge season for the football club," said the Scot.
"We want to stay in the Premier League and get more finances from it and that's the reality of it.
"I'll do everything I can to get people in but if not I'll go with the group I've already gone with."
Norwich moved 10 points clear of the relegation zone with .
Striker Morison secured the win, coming off the bench to net his seventh goal of the campaign.
"He's been brilliant," said Lambert. "He's come here and led the line brilliantly for the best part of 16 games.
"I gave him a rest but the lad's come up trumps again. He's another one that hopefully keeps his career going."
