Adam Johnson believes Manchester City's 5-1 demolition of Spurs at the start of the season was a one-off and will not be repeated on Sunday.
Edin Dzeko notched four goals in the hammering at White Hart Lane in August but Spurs have bounced back to become Premier League title contenders.
While Johnson is determined City should maintain their perfect home record on Sunday, the former Middlesbrough man accepts it will be much tougher to beat Harry Redknapp's side this time around.
"That was a one-off," he said of the White Hart Lane romp.
"We humiliated them with some of the football we played. I don't think many teams would have got close to us. The passing and movement was staggering.
"But the fact is they have some top players, a squad packed with quality, and are playing much differently now."
After opening up a three-point lead on Manchester United and a five-point advantage over Spurs, not finishing the season as a champion would be difficult for Johnson to digest.
"I would be devastated if we didn't win it," he said.
"Most of lads are not thinking about it but we are three points clear, so from this position, it would be devastating not to do it."
Yet Johnson knows that City are not the neutrals choice for a new name on the trophy.
"Maybe because we have spent so much money, people think we are trying to buy the title," he said.
"Tottenham are the team who have nothing to lose and all the pressure is on United and City.
"But the pressure is on whoever is up there to sustain it. If Tottenham do that, there will be massive pressure on them.
"In the last four or five games, when things are still tight, that is when we can see who will hold their nerve."
