The Clarets have enjoyed a week off ahead of Sunday's clash, while Spurs played in the Europa League on Wednesday night.
Speaking to the club website after the draw against West Brom last weekend, Westwood said: "We wanted to go unbeaten.
"The main thing we said to ourselves before this week is not to get beaten by any of the teams.
"We started the week on fire against Palace and then dug in against Fulham.
"It was big for us not to lose against Fulham and it was big not to lose on Saturday.
"We've done that, all being the performance wasn't what we wanted, and we move on.
"We've got a free week now, which we haven't had a for while, so we move on and look forward to Tottenham."
