Forster has been involved with England a number of times under Roy Hodgson in the past two-years, though only made his debut at the end of 2013.
With Joe Hart set to travel as number one to Brazil, the other two goalkeeping spots look wide open with Forster, Ben Foster and John Ruddy all in contention.
Forster is hopeful he will be on the flight to South America come June and he feels that his performances in the Champions League for Celtic have played a huge part in him being in contention.
"We have had some great nights and everyone sees what the nights are like and on a personal note that has helped me get into the England squad, without those I don't think I would have got in," he told Weekend Warm-up.
"Playing for Celtic is a bit like playing international football, because you have got long periods of inactivity at times, then you might have a save to make but you have to be switched on and it maybe about making just one save - so there are similarities and I think that benefits me."
Forster admits it has been hard not thinking about a possible place at the World Cup.
"Obviously it plays on your mind, it would be fantastic to go, a dream to go but obviously it is not my decision and all you can do is play as well as you can and hopefully at the end of the season you might get that text and call letting you know you're part of the squad, it is what every English player dreams of and that would be an honour for me to be part of.
"We have worked so hard over last two years to qualify and to be part of world cup in brazil is a once in a lifetime opportunity."
Forster, who came through the youth ranks at Newcastle United but never got the chance to feature in the Premier League with them, admits he would relish the prospect of playing in the English top flight.
"Hopefully one day I will get the opportunity to play in the Premier League, it will be a fantastic test, it is what every kid dreams of - so it would be fantastic if that days comes along," he admitted.
"It is a fantastic league and this year is one of the best in a while, so much happening at both ends of the table and a few unexpected teams fighting relegation and the title, and it is has been a thrilling year and the coverage Sky gives it is second to none, it is brilliant to watch and the quality of football is fantastic."
Forster is delighted with his form for Celtic this season which saw them break the domestic clean-sheet record.
"I think it has just been the progression from last year, if you see the league the consistency we have had and the manner in which we have played, the clean-sheet record was nice.
"It was one of them things, it came out of the blue - we didnt really talk about it but then journalists started talking about it. It was nice to break the Scottish one and we weren't far away from the UK one but we are obviously proud of what we did.
"The manner and how we play football has really improved."
