Blackpool secretary Matt Williams has confirmed the club are keen to extend David Vaughan, Stephen Crainey and Matt Gilks' contracts beyond the end of the season.
The trio's deals expire next summer and they have been key performers for manager Ian Holloway this term following promotion to the Premier League.
The players can negotiate moves elsewhere from January if they wish, something Blackpool are keen to avoid having made a lively start to the new campaign.
The Seasiders have a number of players whose contracts expire next summer, however, they have earmarked the first-teamers - including Vaughan, Crainey and Gilks - as priorities.
"There are quite a lot of players without an option but the main ones, in the first team at the moment, are Crainey, Vaughan and Gilks," Williams told the Blackpool Gazette.
"I know the chairman is looking at those, where we are at with them, and he is keen to keep all three, particularly given their form."
