Bacary Sagna has talked up the impact of Olivier Giroud at Arsenal.

Sagna has been impressed with the speed of Giroud's adaptation to the Premier League, and says he offers a fresh option up front.

"He's totally different," he said. "Physically he's very strong and he has a different style. We used to play with Robin, who was skilful, and previously with Adebayor, who was tall but skinny. Giroud is a totally different striker and we can use him differently."
