Theo Walcott or Olivier Giroud - who should be Arsenal's first-choice striker?

Theo Walcott and Olivier Giroud's good form has given Arsene Wenger a selection headache, so who should be Arsenal's first-choice striker?
We compare the stats and get the views of Sky Sports pundit Charlie Nicholas ahead of their Saturday Night Football clash with Everton...

Arsenal supporters were unimpressed when Arsene Wenger failed to sign another striker in the summer, but after an underwhelming start to the season, the Gunners have hit a hot streak in front of goal.

for me, i think Arsenal should stick with walcott for the sake of his quick legs, and a less performing everton defence will find it more difficylt in contending with the pace of walcott. Arsenal fan's should know better. please leave a comment.
