Vana Koutsomitis and Joseph Valente are both in the final and this Sunday night will go head to head for the Lord Sugar's £250,000 investment.
Following Wednesday's interview rounds, some viewers claimed that the winner had been spoiled after a preview clip apparently showed which of the two finalists Lord Sugar was naming as being hired.
However Lord Sugar insisted it was rubbish and replied to the claims on Twitter: "I get this all the time."
He then went on to refer to his book with an extract explaining: "Very often in restaurants someone will come up to me and say, 'I know who's going to be fired next week. I can tell, because at the end of last week's episode - when they showed you pointing your finger and saying, 'You're Fired!' - I remember who was sitting where you were pointing, so I know [for example] it's going to be Charlie.'
"'Really?' I say. 'Well, actually, maybe that sequence you saw of me pointing my finger was filmed five years ago. But to be fair, let's analyse what you've just said.
"First of all, if the programme hasn't broadcast yet in which you think I fired Charlie, how do you know that Charlie's sitting at that end of the table? He might have been sitting there in last week's episode, but how do you know he'll be sitting there next week?'
"I'd see the person's face drop and they'd walk off with their tail between their legs, disappointed that their theory was wrong."
Even if a clip did show someone getting hired or fired, it could well be a red herring as the show films two alternative endings. The official decision is only revealed in the final with even the candidates themselves kept in the dark over the result.
The Apprentice 2015 final airs Sunday night at BBC One from 9PM.
