The Republic of Ireland international is hoping to keep his place in the Potters side at Wembley on May 14 after helping his team dismantle Bolton 5-0 in the semi-final on Sunday.
Whelan, 27, cannot believe how much the landscape in the blue corner of Manchester has changed since his time with the club.
"That's where I started out. I've got fond memories back there," said Whelan. "It's where I learnt my trade. It will unbelievable to play against them if I'm in the team come the final.
"There's not many there now from my time - only the kitman and a couple of physios from my time.
"I only left about six years ago so to have that kind of massive turnaround is crazy."
