Arsenal's new recruit Olivier Giroud is sure the Gunners can win trophies next season, after signing on the dotted line on Tuesday.

Giroud arrives from Montpellier, where he led the team to a surprise French League title, scoring 21 goals in 36 games. The French striker officially signed a "long-term contract" after completing a medical at Arsenal's training facility on Tuesday, with the fee believed to be around £13 million ($20 million).

Giroud is convinced he can help Arsenal win their first trophy since 2005. "There is a good spirit here, and that is another reason why I chose this club," Giroud said.

"I am confident in the potential of the group and I am convinced that in the future, hopefully next season, we can win something.

"It is difficult in England because there are so many big teams, but that is what gives it its charm, what makes it beautiful.

"It is the hardest league and it won't be easy to impose myself, but I am confident."

Giroud said he was confident of his capabilities to adapt to the English Premier League's style of play. Speaking to Arsenal Player, the 25-year-old said: "I have the weapons to do well here.

"I will need some time to adapt of course, but I am not worried about that. I think I will adapt well.

"I am a player who likes to play, who likes to participate in the game. That is why I think the way Arsenal play will suit me.

"I like scoring goals and Arsenal create a lot of chances, so if I do well, then we will do well.

"Of course, there are big strikers here, it is a big club and there will be a lot of competition for places, but it is up to me to win my place.

The Frenchman said he was looking forward to working under compatriot Arsene Wenger. "The manager has always been about developing and I hope he can continue to do that with me too.

"I can see what happened to me until now and I hope to continue to progress and show that I can impose myself at the top level.

"It has been great, right now I want to live it to the full, and I will savor this chance."
