Dons boss Derek McInnes today confirmed there is still time for players with their futures undecided to earn new deals.
Aberdeen have four players on permanent deals set to expire at the end of the season.
Another four have loans ending in the summer.
With eight league games left and a Scottish Cup semi, McInnes insists deals can still be won.
He said: “There are loads of games and loads of opportunities for players who would like to be here longer to still show that.”
World Cup-bound Icelandic international Kari Arnason’s contract is up at the end of the campaign.
The defender has already confirmed he wants to remain at Pittodrie.
Versatile defender-midfielder Anthony O’Connor’s deal also expires in the summer.
McInnes was keen to re-sign O’Connor, who has admitted he could wait until the end of the season to assess his options.
Others with deals up include striker Nicky Maynard, who would appear set to move on as he has yet to score this season.
Keeper Danny Rogers also has a deal up but was pushed out of the starting line-up by on-loan Newcastle United keeper Freddie Woodman.
Along with Woodman, the loan deals for three players will end – Greg Stewart (Birmingham), Dominic Ball (Rotherham) and Chidi Nwakali (Manchester City).
McInnes has previously admitted he would be keen to continue working with Stewart.
Definitely leaving Pittodrie in the summer is on-loan Celtic attacker Ryan Christie as Hoops boss Brendan Rodgers confirmed he would return to his parent club.
Midfielder Kenny McLean will also move to Norwich City having signed a three-and-a-half year deal in January. He was loaned back to the Reds.
On summer signings, McInnes said: “There is a lot of work being done behind the scenes.
“Other managers have talked about the summer but for me it is about the here and now.
“I am more just focused on trying to get results.”
Meanwhile, Aberdeen this week received a major boost with the return of No1 keeper Joe Lewis from injury.
Lewis, 30, played all 90 minutes for the Dons’ U20s in a 2-1 league win at St Mirren.
Lewis had missed the last 10 games having undergone surgery on knee ligament damage sustained in a 2-0 loss at Ibrox in January.
On-loan keeper Woodman kept a clean sheet in the 1-0 defeat of Dundee at the weekend. The 21-year-old also saved three spot-kicks in the 3-2 penalty shoot-out win over Kilmarnock in the Scottish Cup quarter-final replay.
McInnes is delighted Lewis is back but also praised the contribution of England U21 international Woodman.
He said: “Having Joe back in training is a real bonus and ahead of schedule slightly.
“But Freddie has done very well for us, for a young boy to come in and show real confidence.
“He also had a very good save to make against Dundee at 0-0.
“Freddie is very good at making himself big and getting his timing right.
“It is a good situation to be in as we have three very good keepers.
“They are there to play their part.”
