Leicester City will be crowned Premier League champions if they win this weekend after Craig Dawson's header held Tottenham to a 1-1 draw against West Brom.
Spurs' surprise slip-up at White Hart Lane means Leicester are seven points clear with three games remaining and the Foxes' fairytale will be complete if they beat Manchester United at Old Trafford on Sunday.
Mauricio Pochettino's men looked on course for another comfortable victory when Dawson bundled in a first-half own-goal, but the defender redeemed himself, heading home with 18 minutes left to leave Tottenham's title hopes hanging by a thread. A disappointing night for Spurs could become worse too as Eric Dier was forced to leave the field following a clash of heads with Dawson in the second half, while Dele Alli may face a retrospective ban for appearing to punch West Brom's Claudio Yacob.
Pochettino couldn't hide his disappointment afterwards, saying: "We were unlucky in the first half and created a lot of chances, but this always happens in football.
"We allowed them to believe and we conceded a goal, but I am very proud because it was a big effort.
"We still need to believe. Seven points is difficult, but we still need to fight in the next three games. We felt comfortable on the pitch and created chances, but we lost control of game and allowed them to create chances. But I think we deserved the three points.
"Mathematically it is still possible. I have nothing to complain about and we need to be strong in our mind and prepare for the next game. It is difficult, but we need to fight for the points. We are not going to give up. We understand it was a game we must win. I must now lift the players for the game against Chelsea."
Spurs striker Harry Kane hasn't thrown in the towel yet, but he admitted his side missed too many chances.
"It has not gone," he said. "We need to keep fighting. We felt we needed to win this game so we are disappointed.
"We had enough chances in the first half to put it to bed, but we weren't good enough in the second half.
"We felt we could easily have won the game if we played in the second half like we did the first. It is football. All we can do is keep fighting.
"We have Chelsea next. Hopefully Man United can do us a favour."
West Brom boss Tony Pulis said: "Tottenham dominated the game and we sat back while they danced around us at times. The best thing was we came in 1-0 down at half-time. It became a more open game in the second half and I am really pleased with the players."
