The 23-year-old was linked with a move to Spurs throughout the entire summer transfer window but a hamstring injury in August saw them back out of the race.
Chelsea looked set to sign him on deadline day but the England international pulled out of a £35 million switch despite arriving at the club to undergo a medical.
It now remains to be seen whether Tottenham renew an interest in January but speculation from The Mirror in July suggested that Barkley wanted £150,000-a-week in order to join Mauricio Pochettino's side - more than Harry Kane's wage.
And although former Premier League goalkeeper Hislop believes that a transfer to North London will materialise, the ex-Newcastle and West Ham ace says that Barkley must be willing to compromise first.
He told ESPN when asked if Barkley will join the Lilywhites: "He wanted to be the highest-paid midfielder at Spurs and that's not going to happen.
"I'm not absolutely certain [he would start]. I'll put this down as a hit because I think it'll happen, but he's got to come down off his high horse a little bit to make it happen."
