New Chelsea signing says speaking with Conte gave him confidence to seal move to the west London club.
Antonio Conte helped convince Olivier Giroud to move to Stamford Bridge from the Emirates on deadline day.
The new Chelsea frontman signed an 18-month contract for a reported fee of £18million.
"The most important thing was talking with the coach, Antonio Conte," Giroud, who won three FA Cups with the Gunners, told Chelsea's official website. "I felt like he really wanted me and he really wanted to work with me.
"I wanted to sign for Chelsea and nowhere else. I really wanted to play more. I wanted to stay in the Premier League, and Chelsea for me is perfect because I can even stay in London.
"But the first reason is the sporting challenge. That has always been my first priority. Everything is here for me to be happy.
"My ambition is to win some trophies. That's why I am playing football. I am a competitor and I want to win again and again.
"I want to score as many goals as I can to help the team to always reach our target and to be as decisive as I possibly can be."
Giroud is also looking forward to working with Conte having watched his passionate approach to matches on the touchlines.
"I don't know him very well but I like the positive energy he brings from the side of the pitch, always supporting his players, talking to them," the Frenchman said. "I think communication is massive in football and in all sports in general.
"For me, the relationship you have with the coach is very important. His tactical philosophy is very good because he is Italian. Chelsea is a strong team defensively and they are quite efficient up front with great players, so I think I will enjoy it."
On his chance to play Champions League football once more, with the Blues facing Barcelona in the last-16.
He said: "The Champions League is massive for a football player. There is nothing above it when you're playing for a club.
"There will be two nice games against Barcelona. We know their qualities and I think everybody will need to be 100 per cent to go through. It will be very exciting and I'm looking forward to it."
