Mauricio Pochettino has refused to concede the title race is over despite Spurs dropping points at home to West Brom on Monday night.
The draw against the Baggies means Leicester can now win the Premier League with victory at Manchester United on Sunday, as they sit seven points clear of second-placed Tottenham with just three games remaining.
Craig Dawson’s own goal had put the hosts ahead in the first half but the defender made amends, heading home with 18 minutes left, to leave Spurs’ title hopes hanging by a thread.
“It is not over,” Pochettino said. “The gap is seven points and we have ahead three games.
“It is true that it is very difficult, more difficult than before the game, but we still believe and we are still fighting.
“We have to hope Leicester drop points and we get three points at Chelsea (next Monday).
“It is important to still fight. The objective is still there. It is more difficult than before but the gap with Arsenal and Manchester City (in fourth and third) is five points and we need to keep this gap.
“It is important to win in case Leicester drop points so we can win the title.”
