Vice-captain Graeme Shinnie today urged the Dons’ out-of-contract stars to follow his lead and sign new deals.
Shinnie, 25, penned an extended contract during the January transfer window tying him to Pittodrie until summer 2019.
Skipper Ryan Jack, Niall McGinn, Ash Taylor and Peter Pawlett all have deals set to expire at the end of the season.
Republic of Ireland cap Jonny Hayes penned a one-year extension last month until 2019.
Andrew Considine recently committed until 2019 by signing a two-year contract extension.
Shinnie hopes the remaining four can commit as well to help the Reds push for honours.
He said: “Keeping the squad together can only be good for the whole club.
“So far so good with some of the players signing.
“Hopefully the rest of them can also commit their future so we can build on what we have here.
“What we have here is certainly something good and we want to build on it.”
Shinnie still had 18 months left on his contract when he signed the extension.
Likewise leading goal-scorer Adam Rooney had two-and-a-half years on his deal before adding another year last summer until the end of the 2019-2020 campaign.
One lure the Dons can offer players out of contract next season looks certain to be European football.
Aberdeen have taken command of second spot having opened up a six-point advantage over Rangers.
The Reds can extend that to nine points, albeit potentially for less than 24 hours, as they host Motherwell at Pittodrie on Saturday.
Rangers travel to Parkhead on Sunday to face champions elect Celtic. The Hoops have taken 79 points from a possible 81 this season.
Shinnie admits to frustration there could be no repeat of the Dons’ title challenge to Celtic of the previous two seasons.
Aberdeen’s fight is for second and Shinnie aims to confirm that runners-up finish and the mantle of Scotland’s second force as soon as possible.
Shinnie said: “Our main focus at the start of the season was to try to push Celtic as far as we can.
“Celtic have obviously had a strong season and it has been very tough trying to keep up with them.
“This season Celtic have only drawn one league game and won the rest which has been hard for us.
“Our fight now is for second and we are trying to cement that as quickly as we can.
“We have to focus on second place but know we have a fight on our hands to get it.”
Looming on the horizon is a Scottish Cup semi-final clash against holders Hibernian at Hampden.
The SFA have confirmed that match will kick-off at 12.15pm on Saturday, April 22.
The early start is because the semi is being shown live by Sky Sports and BBC Scotland.
It means an even earlier start for the Dons fans, but it’s something they have become accustomed to having to cope with because of the demands of the television companies.
Sky will also screen the Celtic v Rangers semi on the Sunday, from noon.
The Dons’ cup-tie will see Shinnie go head-to-head with his older brother Andrew, who plays for Hibs, something he is looking forward to.
The Don said: “It will be a great occasion and something we will both be able to look back on – although who remembers it best depends on who wins.
“There won’t be any distraction because he is my brother.
“During the game he is just going to be like any other opponent.”
