Spurs – winners at Stamford Bridge for the first time in 28 years last season – are up after that in the top flight.
Giroud said: “We want to qualify in every single competition, so it is going to be a massive game against Spurs.
“We need momentum and to keep going that way. So we are looking forward to it.
“I have had to deal with pressure throughout my career. I played big games with my clubs and the national team.
“In these kinds of moments, you need to think collectively and be positive.
“In Sweden (against Malmo), that's what we showed on the pitch.
“Even though the score could have been better, we are pleased with the win. We have got strong characters in the team.
“A few players tried to bring leadership to the team and the result showed it worked."
