Tottenham currently have a two point advantage over their North London rivals, but their form going into the final day is poor.
Spurs have failed to win any of their last three matches, and they will be without some significant players against Newcastle.
Arsenal, meanwhile, only have a home match against rock bottom Aston Villa left to play, and it is widely expected that they will pick up three points in the fixture.
Spurs, therefore, are likely to have to avoid defeat against Newcastle to ensure that they finish in second spot, which is far from a foregone conclusion.
Newcastle may need to win the match to avoid being relegated from the Premier League, but Curbishley is confident that Spurs will have too much for Rafael Benitez’s side.
“I have got a feeling that because of the week Spurs have had they will go to Newcastle and get the result,” he said. “The group of players there will be disappointed with what’s gone on.
“I think Spurs will get the result.”
Tottenham’s task of winning at St. James’ Park is likely to be made much easier if Sunderland can pick up a victory in midweek.
The Black Cats can relegate Newcastle if they beat Everton tomorrow, meaning that the Tynesiders would have little to play for against Spurs other than pride if that’s the case.
