Mauricio Pochettino's team were recently considered out of the race involving Liverpool and Manchester City, but four dropped points from the former has left the North London outfit just five points adrift in third place.
Son Heung-min's return from international duty has also provided Pochettino with a timely boost, and the South Korea international netted the only goal as Spurs defeated Newcastle United last weekend.
Ahead of this weekend's match, Sports Mole assesses how Son has previously fared against Leicester.
Son has been involved in matches against the Foxes on eight occasions, with four wins and two draws being recorded in all competitions.
The attacker has four strikes to his name but each of those goals - including a double in the 6-1 thrashing in 2017 - have come in games at the King Power Stadium.
Each of Son's three assists have also come in the East Midlands, leaving him with a remarkable return at the home of Sunday's opponents.
However, Son has not contributed in 194 minutes of football when playing against Leicester at White Hart Lane or Wembley Stadium.
