Harry Redknapp’s men currently sit third in the table, seven points behind leaders Manchester City with a game in hand, having won eight of their last 10 league matches.
And Caulker, who cannot play himself on Saturday, believes the north Londoners are entitled to be dreaming of title glory, although he is backing his current team-mates to make life difficult for them.
"There is great depth in the Spurs squad and no reason why they can't go on and push on for the title,” the 20-year-old told The Sun.
"It's difficult for me, because if they do go on and win the title, I'm sure they will be looking to bring in new players.
"I wish the boys all the best but they will face a massive test on Saturday.
"It will not be a foregone conclusion."
