Hull City are holding talks with Liverpool over the proposed permanent acquisition of defender Daniel Ayala.
The 20-year-old made 12 appearances in the Npower Championship for the Tigers last season, and Nigel Pearson remains hopeful a deal can be struck to bring Ayala back to the KC Stadium.
"I never rule anything in or out but I would say it's unlikely," said the Hull boss.
"Ayala is a target and we've put a bid in. The clubs are in discussions and we'll see where it takes us.
"As always the criteria of how you add to your squad is governed by finances."
Ayala has played five times for the Liverpool first-team since moving to Anfield as a teenager in 2007, having rejected professional terms with La Liga out Sevilla.
Liverpool were required to pay compensation to Sevilla before Ayala could complete his switch to Merseyside and, upon joining the club, he quickly moved through the ranks.
The Spaniard has since spent loan spells with Hull and, latterly Derby, but it remains unclear whether or not he has a long-term future with Liverpool.
