Below is an excerpt from the Journal de Montreal article by Marc De Foy who interviewed Saku Koivu about his future with the Canadiens:

“The uncertainties linked to the salary cap make it more difficult nowadays to spend our entire career with one team,” said Koivu yesterday.
“However, I am very proud to have played only with the Canadiens since the beginning of my career.”
“It would be a great honor to finish my career with the Canadian.”
