The midfielder is enthused that Spurs are getting into the right positions to score goals, and hopes they can take their chances against the Cheries.
The Cherries have taken just one point form their last three games in the Premier League, with their last league game seeing them on the receiving end of a 5-1 defeat to Manchester City.
They are sure to be keen to end that poor run of form and bounce back strongly from the disappointing defeat to Manuel Pellegrini’s side, and Dier says Spurs are anticipating a tough game on the south coast.
“It’ll be very tough,” he told tottenhamhotspur.com.
“They’re a good side and I think they’ve proved a point to a lot of people already this season. Obviously they’ve got a few injuries now and they’re going to be up for it like every game, but we’ve got to be just as determined as them and go and get the three points.”
The midfielder is also hoping that the side can put away their chances when they come along with the side lacking a cutting edge in recent games.
The midweek loss to Anderlecht was a perfect demonstration of this, as they had a number of chances throughout the game to put it to bed, something that has been a problem in several of their game this season.
Striker Harry Kane in particular is struggling to re-discover his form of last year, himself missing a big chance against the Belgians, but Dier is enthused that they are getting in the right positions and wants to make sure they take their chances.
“This is a new game now and we’ll go into it and try to win,” he added.
“I think we’ve been getting in the right positions and we’ve been defending well in most of our recent games so we just need to make sure we take our chances.”
