The 25-year old former Newcastle United goalkeeper is continually being linked with a call-up to the England squad for the 2014 World Cup despite playing in what many critics believe is a subpar competition.
Forster is undoubtedly the best keeper in the Scottish game at the moment but needs to prove himself to Three Lions boss Roy Hodgson who has the likes of Joe Hart (Manchester City), Ben Foster (West Bromwich Albion) and John Ruddy (Norwich City) to choose from for Brazil 2014.
In regards to the potential England selection, Forster has made it clear that the only thing in his control is to stay in good form for the Hoops as they chase a third-straight Scottish premiership.
"Obviously, you're looking ahead towards the summer and I am just looking to play as well as I can between now and the end of the season as that would give me the best opportunity of getting on the plane to Brazil for England," he told Celtic View.
"I'm going to try and keep on doing what I have been doing and keep working on the aspects of my game which I feel need it. I also want to keep looking after myself physically and improve on that side of things.
"So those are my aims for the rest of the season - keeping the standards high and continuing to perform at that level."
