Potters boss Tony Pulis has often opted to switch between the two when selecting his starting eleven, though Begovic made 22 Premier League starts to Sorensen's 16 last term.
And, whilst the 36-year-old admits that the keeper who loses out will be frustrated at being left on the bench, he accepts that Pulis has a tough decision to make.
"I don't think much has changed from last season," Sorensen told The Sentinel.
"There are two good keepers fighting to be number one. It's a good situation for the manager.
"It will be frustrating for one keeper, but the manager has proved he is willing to go to either keeper and is willing to give us both a fair chance."
Sorensen is also eager to get back to business, after being ruled out of Denmark's Euro 2012 squad following a late injury.
"I was fine within a week or ten days of the injury. It just came at the wrong time for me," he added.
"It was more about the uncertainty because the final squad had to be selected. I was devastated to be so close having worked so hard for so long.
"But the manager was fair and explained why he made that decision.
"I can see why he wanted everyone fit. It could have kept me out for two weeks and I would have missed all the games.
"I was down about it, but I am part of the team and was kicking every single ball as I watched the games."
