City are currently 11 points clear at the top of the table and on a 16-game winning run in the Premier League. Spurs, who finished second last time out, currently find themselves an incredible 21 points behind the pacesetters and face a fight to even qualify for Europe.
Speaking to 'Sky Sports', the Dane admitted that the title race is as good as over after just half a season and voiced his disappointment with Spurs' recent form.
"We have shown before, with the team we have and the players we have, that we should have done better, and we could have done better," he admitted.
"Now we have a week to prepare for Burnley and they are above us, so we need to be in top form.
"I think you need more than a miracle to catch City, but we are focused on ourselves and trying to come into a better position than we are in now.
"Of course we need to improve a lot but City is a long way ahead."
Despite Mauricio Pochettino's side struggling domestically, they have excelled in the Champions League, winning their group ahead of Real Madrid, although Eriksen still believes it is too soon to think about winning Europe's premier club competition.
"It is a long run and there are some very difficult teams in between," said Eriksen. "We will test ourselves in the first game against Juventus and see where we are at.
"There will be some fun games to play and hopefully some exciting times. We will see how far it ends up.
"To say we have to win Champions League from where we came from to where we are now is a bit too big I think."
