Tisdale told BBC Devon: "I'm happy at Exeter - the job's not finished yet, so I haven't been swayed by any vacancy.
"I'm pretty committed to where I am at present, so on Saturday I'll be an Exeter City manager."
He added: "Southampton is a former club that I spent a long time at, and I'm a follower of the Saints."
During the summer, Tisdale was also linked with the manager's post at Championship side Swansea City, before the job eventually went to Brendan Rodgers.
