Northern Ireland’s play-off clash with Bosnia has been postponed indefinitely due to the coronavirus crisis.
“As time goes on, it’s probably going to be unrealistic that Michael stays in charge,” said Aberdeen’s McGinn.
“We obviously want Michael to be there,” he added.
“I think him more than anyone deserves a huge send-off and what a send-off it would be to qualify for another major tournament.
“He’s been there before with us and what an unbelievable achievement that was, for the coaching staff and the players, and it meant so much to the fans, so to see Michael get another opportunity to take us to another major tournament would be brilliant.”
