The foundations for this historic heist are already in place, with Celtic leading the SPL, in the semi-final of the League Cup, preparing to meet Raith Rovers in the last 16 of the Scottish Cup, and looking longily at their last 16 Champions league ties with Juventus.
However, from his lofty position, the giant keeper can see that it can all slip through their fingers if the standards which got them to this point are not maintained.
So, Celtic's most consistent player this season has his sights set on more of the same when the action restarts this weekend.
Forster believes the training and golf break in Marbella, which will conclude with a friendly against Steaua Bucharest tonight, will tee them up perfectly for the long drive to the finishing line.
He said: "We have achieved what we wanted up until now this season. We're still in four competitions. It's just a matter of getting straight back on the boil as soon as we start up again.
"We've opened up a gap in the league and we want to keep it that way. It's been a great season so far for everyone in the squad.
"Goalkeeping coach Stevie Woods has played a huge part in how I have progressed. He can never do enough for you, training wise. He'll stay out all day every day if you want. We've worked really hard on every aspect of the game, and huge credit has got to go to him for all the time and effort he has put in."
Due to his height, Forster is used to being noticed wherever he is. But it is the size of his growing reputation that has caused a few second glances around the club's training base here in the Costa Del Sol.
He hit the headlines around Europe for his performances against Barcelona in the Champions league Group Stages, and was featured heavily on the front pages of the newspapers in this football-obsessed country.
Forster looked sheepish as he reflected: "A couple of my mates sent me photographs of that, so it was nice. Some people in Spain seem to like me.
"You've just got to ignore that, although it is nice to get the recognition when you are doing well. You can't believe all the hype. That's all in the past now. It's all about what we do from now on."
Which includes trying to knock Italian cracks Juventus out of the Champions League to book a quarter-final place for the first time in Celtic's history.
The ties will pit Forster against one of his all-time heroes, Gianluigi Buffon. And the Italian international keeper has joined the throng singing the big man's praises this term.
"You could have worse people commenting on you," is Forster's reaction to that.
