Liverpool manager Jurgen Klopp says his team needed "luck" to beat Tottenham, but added that "desire and attitude" is driving their Premier League title bid.
Toby Alderweireld's late own goal at Anfield on Sunday moved the Reds two points clear of rivals Manchester City, who have a game in hand.
Liverpool are attempting to win their first top-flight title for 29 years.
"We compete with Manchester City. Tell me two better teams at the moment - and we compete with them," Klopp said.
"I told the boys after the game there are 500,000 ways to win a football game, and today was rather ugly.
"But without a bit of luck you cannot be in the position we are in.
"We are top of the table. If we are there at the end of the season it will be down to will, desire and attitude."

Defending champions City will regain top spot if they defeat strugglers Cardiff at Etihad Stadium on Wednesday (19:45 BST kick-off).
Pep Guardiola's side became the first team in English top-flight history to reach 100 points when they won the league last season.
However, Klopp's side are also breaking new ground and their tally of 79 points from 32 fixtures eclipses the 76 they had in 1987-88, when they went on to win their 17th of 18 top-flight titles.
"If we are top of the table after the last matchday, it would be a championship of will," said Klopp, who pinpointed the reaction of the Anfield crowd to Lucas Moura's equalising goal with 20 minutes left on Sunday as being crucial to his team.
"Nine months ago, we started and wanted to go for the highest stakes in two competitions. We did it our way. For all the points we have now, we work really hard.
"It is not important when you score but what it is on the scoresheet afterwards. Momentum is not a coincidence - it is something you take, you keep and you use.
"We get used to situations bit by bit. The whole stadium... it was the best performance of a Liverpool crowd after an equaliser since I arrived."
