Isaias hopes his decision to re-sign with Adelaide United will trigger his team-mates such as Marcelo Carrusca and Dylan McGowan as well as coach Guillermo Amor to do the same.
The Spanish midfielder inked a three-year deal with the Reds late last week, while speculation mounts about several other players.
McGowan has been linked with clubs abroad, while James Holland has already flown to China for a medical with Lioaning Whowin.
However, Carrusca along with Sergio Cirio, Eugene Galekovic, Michael Marrone and Iacopo La Rocca are all out of contract at season’s end.
“I think the club is working on that,” Isaias said.
“I think they’re making a good project long-term. I think it’s good for the club.
“I hope a lot of players want to stay with me and make a competitive team for the future.”
Title-winning coach Amor’s future is also uncertain, given he is out of contract at the conclusion of the 2016/17 campaign.
“I think he’s a very good coach,” Isaias said.
“Hopefully the club can keep him here but it’s something the club will manage with him. It’s his personal decision.”
Adelaide already lost championship winning players Craig Goodwin, Stefan Mauk, Bruce Kamau, Bruce Djite and Pablo Sanchez in the off-season.
