Although Manuel Pellegrini's team have lost four away games, they do possess a 100 per cent home record.
"Every time we've suffered a defeat we've had a couple of weeks to mull it over and it's made us even more hungry to get the win when we do have a game," Townsend said.
"Everyone is focused on getting a good result on Sunday."
Spurs are undefeated in three Premier League away trips since their 1-0 defeat to North London rivals Arsenal.
"City is going to be a hard game regardless of the team they play and if they're at home or away," the Spurs winger added.
"It's always going to be a tough game so it's up to us to match them and hopefully get the win."
