The Bluebirds have moved to bring in four new additions since earning promotion from the Championship in May, splashing out around £28m to sign Josh Murphy, Alex Smithies, Greg Cunningham and Bobby Reid.
In a further boost ahead of their Premier League return, Cardiff have also announced new deals for a string of players, while Aron Gunnarsson has verbally agreed to stay on following the expiration of his existing deal.
Warnock now intends to take advantage of the loan market, with Liverpool midfielder Marko Grujic among those on City's radar.
"We worked really hard to try and tie all the lads down from the club to give them an incentive to stay in the division next year," he told the club's official website. "We're delighted people like Joe Ralls, he deserved his extension, he's been magnificent for me. He goes about his job without any problems at all for a manager.
"We're still hoping to get a couple of loan signings in. We've got people like Lee Peltier, Matthew Connolly, Sean Morrison who's extended his contract, and he didn't even need asking really. It's fantastic. They all want to be a part of it. I must admit, when you look at Nathaniel Mendez-Laing and Junior Hoilett already doing that, I think it's an exciting time for us.
"All they can do is do their best. I've said to them, 'don't worry about it', because they say I'm not a Premier League manager either so don't worry. Not forgetting Callum Paterson and Brian Murphy. Murph's unbelievable in the dressing room and he's still a really good agile keeper. I'm delighted to have him around.
"What can you say about Paterson? He's not a full shilling is he. I asked him what number he wants. He said 'I want number 13 boss'. Who would have number 13? Only Paterson. But he had a super season last year and the fans have taken him on board. He'll be an important part."
Cardiff returned to pre-season training last week ahead of their Premier League opener against Bournemouth on August 11.
