Roy Hodgson will announce his squad for the August 15 friendly with Italy on Thursday.
Butland can be hopeful of keeping his place, having created a positive impression as third-choice keeper during Euro 2012 and has enhanced his reputation hugely during GB's run to the Olympic quarter-finals.
So impressive has Butland been that some have suggested England have finally found meaningful competition for Hart.
It certainly looks pretty obvious he will not be hanging around at Birmingham much longer.
However, ahead of tonight's [Saturday] last-eight clash with South Korea at the Millennium Stadium, Butland has played down the comparisons.
"I enjoyed being part of the England set-up because I gained so much experience and hopefully that will continue," he said.
"But I am still only 19 and I need to play games before I can ever think about testing Joe because he is one of the best keepers in the world at present.
"All I want to do at the moment is enjoy this Olympic experience and see where it takes me."
Twelve months ago, the 19-year-old was preparing to embark on the first of two spells on loan with Cheltenham.
When the domestic campaign ended his only senior action was with the Whaddon Road outfit.
Now Butland has found himself turning out in front of massive crowds at Old Trafford, Wembley and Cardiff, with another certain to follow in the Welsh capital tomorrow.
And, with impressive maturity, he is taking it all in his stride.
"I thrive on pressure," he said.
"I love big games. All I have wanted to do since I started was play for England and win tournaments.
"I do get nerves at times. Before the first match at Old Trafford was the most nervous I have ever been in my life.
"It took me about 20 minutes to get used to it but after that I was fine. It is something to enjoy, not be frightened off."
If South Korea are seen off, the odds are GB will face hot favourites Brazil in the semi-final.
It is not a mission he would be scared of.
"If we are going to play in this tournament, we will have to play the best teams," he said.
"It doesn't matter whether it is the final or semi, we are going to have to play Brazil if we want to win the competition because I don't expect them to get knocked out."
