Owen is believed to be considering a deal from the Magpies hierarchy and Guthrie wants the process hurried along so they can secure the England international.
"He is massive - you saw that at the weekend (against Portsmouth). One chance, one goal. You need those players," Guthrie said.
"We need to make it a bit easier on ourselves with people like myself getting goals to help him out."
"The contracts are important, especially with the players who are concerned," he added.
"Everyone knows the situation with those players, it is just a case of them sorting it out themselves.
"But it's nice that with all that's going on, we can still go out there and perform, even with people who have contract talks hanging over their heads."
