Dick Advocaat has rejected the opportunity to become permanent head coach at Sunderland.
St Mirren captain Jim Goodwin has urged Jeroen Tesselaar and Nigel Hasselbaink to show some loyalty to the club and sign new contracts.
Saints manager Danny Lennon is waiting on an answer from the Dutch pair's agent after offering them extensions.
Goodwin turned down a more lucrative offer from Hibernian in January to extend his Saints contract, and left-back Tesselaar and forward Hasselbaink are the only unsecured players in Lennon's first-team pool.
"They are taking their time a wee bit," Goodwin said. "I hope they get it sorted soon. They are two important players for us and I just hope they do the right thing.
"Obviously they better sort out their own finances and what have you but I think the club have been good to them since they came here.
"I think the manager and Tommy Craig have improved them as players and I hope they do like I did in January and reward the manager and Tommy with a bit of loyalty. Hopefully they will sign on for another year or two at least."
Lennon also believes the pair have benefited from their first season at the Paisley club, who could finish seventh in the Clydesdale Bank Premier League if they win at Aberdeen on Saturday.
"We made a written offer to the agent in the early part of the week and we're waiting on correspondence," Lennon said.
"I'll certainly be picking up dialogue with the players. We have put the offer in and all we are looking now is confirmation whether it's yes or no.
"They are two players we certainly want to keep. Nigel started the season very brightly and has finished it very strong. Jeroen has been very consistent throughout.
"They have certainly helped the progress of this football club but this football club has developed them into very good, young players.
"I believe another season or two would continue that development."
Saints have already secured their highest finish since 1989 and are looking to stay above Aberdeen and leapfrog Kilmarnock into seventh place, but Goodwin feels they could have done better.
"We started very well and set high standards," the Irishman said.
"Then the middle part of the season we didn't play so well. That part of the season has cost us.
"From the start of the season we maintained we wanted to try for a top-six position. It wasn't to be, maybe teams figured us out and we stopped going for what we were good at maybe.
"I will look back overall and be slightly disappointed. The Ayr United game in the League Cup was a missed opportunity.
"I look back at the amount of draws we had. If we had turned a few of those draws into wins we might have been in the top half.
"We have still made great strides from last year, we're competing for seventh place which St Mirren fans haven't seen for a long time.
"So in that aspect it's been a success but overall there is a tinge of disappointment."
