Norwich City boss Bryan Gunn concedes it could be difficult to sign Jason Shackell and Alan Lee permanently following the club's relegation to League One.
Shackell rejoined the Canaries on loan in February and made 14 appearances for the club, just months after leaving Carrow Road for Wolves.
The defender is now on the transfer list at Wolves, while Crystal Palace striker Lee scored twice in seven appearances after his arrival in March.
Lee had been open to staying with Norwich, but Gunn fears dropping out of the Championship will impact on his transfer plans.
"Signing them both was my hope at the end of last season had we stayed in the Championship," said Gunn.
"But we didn't and it will be tougher for that reason. Financially we need to be realistic.
"These guys have got contracts at a Premier League and a Championship club. They are both under contract for the next two years.
"Being in League One is going to make it more difficult to attract them than it was before. We are investigating it."
