Manager Ole Gunnar Solskjaer has accused some agents and clubs of being unreasonable as he tries to strengthen Cardiff City's squad.
Solskjaer has so far signed three Norwegian internationals since replacing Malky Mackay.
But Solskjaer says attempts to further add to the squad are being hampered by clubs and agents' financial demands.
"They think we've got 'X' amount of money to just give away - of course we haven't," Solskjaer said.
"There's loads of players that I've wanted, maybe had a look at, but the price tag is not realistic."
Forward Jo Inge Berget became Cardiff's third Norwegian signing of the transfer window on Friday, joining from Molde for an undisclosed fee.
"We're talking about three full internationals I've brought in on very cheap prices," the former Manchester United striker added.
"They haven't played in the Premier League but they're all full internationals. I know them because I've had them before so I know their personalities."
Solskjaer could hand Magnus Wolff Eikrem and Mats Moller Daehli full debuts in the FA Cup fourth-round tie at Bolton Wanderers on Saturday.
Despite Cardiff's precarious position at the bottom of the Premier League, two-time FA Cup winner Solskjaer does not see the competition as a distraction.
Solskjaer's only win so far as Cardiff boss was the 2-1 victory at Newcastle United in the third round of the FA Cup.
"I think it's vital to build momentum and confidence," Solskjaer said.
"I hear many say it's a distraction but for us it's another chance to get to know the lads and for the lads to try and implement what we want them to do.
"This is the one game we really want to get to - the final. The FA Cup is massive to us."
