The details of the deal are undisclosed, but it is believed that the former Montpellier man signed a "long-term contract" for around £13 million. Combined with fellow new addition Lukas Podolski, it appears Arsene Wagner is preparing to unleash an offensive onslaught on the English Premier League next season.
The 25-year-old Frenchman is a ruthless striker, using his high football IQ and great upper body strength to punish defenders. He's a predator around the net and his vast skill set causes nightmares for opposing sides.
As you can see in the video above, Giroud is a complete striker. He's good with his boots and his head, scoring goals in every conceivable way. He's an expert at volleys, he's dangerous in the air and he's accurate from distance and in front of the net.
He finished tied for first in Ligue 1 play with 21 goals in 2011-12, leading Montpellier to their first Ligue 1 title in club history. He's also much more unselfish than your average striker, dishing out nine assists last season.
With his versatility and quality, Giroud is the perfect addition to Arsenal's attack. He would form a menacing duo with Robin van Persie, and if the Dutchman decides to transfer, Giroud is a capable replacement.
Giroud will need some time to adjust to his new teammates, but once he's comfortable in North London, Arsenal will be primed to make a run at the Premier League title.
