McGuinness was recruited by his friend Lennon and combines his role at Celtic with being senior manager at Donegal's Gaelic football team.
Lennon's decision to quit the Scottish champions has put a major question mark as to the future of the 41-year-old, who is celebrated in Ireland as one of the most influential innovators in sport. But although McGuinness admitted that he was disappointed to see Lennon leave, he is hoping to stay, no matter who gets the Parkhead post.
"I hope I will stay, but with change there always will be change, so we will see what it brings," he said.
"Whatever person comes in now, I will do my best regardless. I'm following things like everybody else."
