"Certainly, if Mats Sundin changes his mind in the coming weeks and he's interested in joining us, we'll listen," Gainey said.
"Our door is always open to the possibility of adding another player. We have space under the salary cap and if we can find another player that can help our team, we'll enter into those discussions then."
Gainey indicated that things can always change in a matter of moments, and that he'll be ready for any opportunity that arises.
The Habs are not expected to pursue the other superstar will available on the market, Jaromir Jagr.
"I don't know what will happen with him," Gainey said. "I believe he's received offers from two teams. We really like our top [six players]. [Jagr's] not a priority for us."
Gainey also acknowledged his interest in Marian Hossa, who signed with the Detroit Red Wings.
"We had some discussions with his agent," he explained. "But, I don't believe that we were really in the race."
Meanwhile, it appears unlikely the Habs will re-sign center Bryan Smolinski and defenseman Patrice Brisebois.
