Tottenham currently sit second in the Premier League, five points behind leaders Leicester City.
Indeed, the pundit believes you can't discount the north London side, whose spirit and unity sees them 'at one.'
And Keown also believes Tottenham's belief and patience in the face of pressure could prove a crucial factor at White Hart Lane.
Against Watford, for instance, Mauricio Pochettino's men were not fazed despite failing to score for long periods.
Keown told the BBC: "Don’t discount them. They’re at one, they love their manager, they love the players.
"They play in triangles. You put them under pressure but you can’t ruffle them. They play with a belief that eventually the goals will come."
Next up for Tottenham in the Premier League is a huge clash against Manchester City.
At White Hart Lane, Spurs thrashed City 4-1 but, unfortunately for the north London side, City's home record is far superior to their struggles on the road.
