Norwich City have signed Preston midfielder Simon Whaley and Crystal Palace defender Rhoys Wiggins on two-year deals for undisclosed fees.
It means Bryan Gunn has brought in eight players on permanent deals since the Canaries' relegation to League One.
City have also signed Spurs keeper Ben Alnwick on a three-month loan deal.
Whaley told BBC Radio Norfolk: "I don't think Norwich are a League One side to start off with, they're an established Championship team."
"They're potentially a Premiership club, so the challenge of getting promotion to the Championship attracted me to the club."
The 24-year-old former Bury man said he was delighted to complete the move after questions over his fitness.
"I think it's been the longest medical in history, over a week now, back and forth between Norwich, home and London last week as well, it has been frustrating.
"The other night there was an injury picked up on the MRI scan that even I didn't know about, between then, seeing the consultant and getting the results it was a worrying time," he said.
Wiggins was also not bothered by taking a step down after his move from Selhurst Park.
"The biggest concern for me now is playing first-team football week in week out - dropping down isn't a problem, I went on loan to Bournemouth at the bottom of League Two last year," the 21-year-old said.
"I just want to be playing, and I can see Norwich getting back in the Championship very soon indeed."
