Vaughan’s current contract with Blackpool is set to expire next week, but the midfielder has been offered a new deal by the club.
“I know my agent has spoken to Rangers,” Vaughan told STV. “I’ve just got to take it from there and leave it in his hands.
“In Scotland, Rangers are a massive club and they play in the Champions League. So it is an attraction.
“I’ve just got to weigh up all my options and see where it takes me.”
Sunderland, Everton, Stoke and West Brom are also reportedly keen on the former Crewe Alexandra ace.
