I voted for Olivier Giroud as ever since he came back from the injury, earlier in the season he have score good amount of goals (12 at the moment, 3 off the top) and if he could just convert half of the chances he gets in each game, then I could see him in the very top scorers chart at the end of this season.
Giroud is an awesome pick since arsenal could win the league and play excellent football with lots of goals. Giroud always seems to have 2-3 chances to score everytime i watch him play for arsenal.
This. I could imagine Arsenal winning the league this year. Yes, the game against Stoke a few days ago didn't show the Arsenal we have been seeing lately, but then again, Wenger just doesn't seem to have any luck playing at Britania. Arsenal is playing fantastic football, and especially with Özil, who seem to start to do well in the league. And we have to keep in mind, Alexis Sanchez isn't even playing yet - can you imagine how Arsenal will play then?
The only 'real' goalscorer Arsenal has is Giroud - and he is in fantastic form, just look at the game against Liverpool, he truly is a world-class forward.
