Martinez is unhappy with the legacy he was left at Swansea

"Eight players are out of contract and two on loan, that's not right at a club of this calibre," he said after the 6-3 Blackpool loss ended play-off hopes.

"It's a situation I've inherited and want to change, and by early this week we'll know our retain list.

"There are many departments we have to improve, that's always the way, and I've got a clear idea of what we need."

Richard Duffy and Darryl Duffy are the two loan players, and it seems that Swansea are particularly keen to secure the services of the latter, whose loan spell from Hull ends on Monday.

Izzy Iriekpen, one of the out of contract players along with Kevin Austin, Kris O'Leary, Tom Williams, Garry Monk, Adebayo Akinfenwa, Andy Oakes and Steven Watt, says he is keen to stay, but also confident that he could secure a deal at another club.

"I feel that I've done enough," Iriekpen told BBC Sport Wales.

The defender, who was taken off the transfer list when Martinez replaced Kenny Jackett as manager in February, feels that the club's timing of the leadership change could have cost them promotion.

"The new gaffer [Martinez] changed things around and if he'd come in earlier we wouldn't have been in this situation," he said.

"He's a brilliant manager to work under and Swansea will push on under him, there's real hope for next season at this club."

The Blackpool defeat was just the second in 12 games under Spaniard Martinez.

"It was a strange game because we needed more than a win," Martinez told BBC Sport Wales.

"We tried and gave everything and you have to be proud of the players, while the fans were just magnificent.
