The American forward is hopeful Spurs can end their London rivals' unbeaten start to the Premier League season when they visit White Hart Lane on Saturday.
Spurs have posted victory in their last four league matches and recently ran out 3-2 victors against perennial title challengers Manchester United, winning at Old Trafford for the first time in 23 years. The former Fulham forward insists it is vital to keep that run of form up when they face the Blues, who have yet to lose a Premier League game this term.
"It is going to be an important game, because the table is so tight," Dempsey told Sky Sports News. “You have to take care of your home games and try and get as many results as you can. We want to continue this run of positive results, so we know it is going to be a tough test, but we are all excited, and we have everyone back from fitness now and we are looking to make the most of this game."
The 29-year-old Dempsey, who is getting set for Tuesday's CONCACAF World Cup qualifier against Guatemala, went on to express his happiness with life at the club following his 6 million pound move from Fulham on deadline day, but he underlined his desire to contribute more in terms of goals and assists.
"I feel like I am settling in," Dempsey said. "I have played in seven games, and six starts - with a goal and assist in the league and I would like better numbers than that, but at the same time I am feeling good and playing consistently. I am playing well, but I just want more goals and assists as it feels I am contributing more."
