Theo walcott more effective this season ????

To be honest, I don't know how Wenger switches between Arshavin, Walcott, Chamakh and Van Persie, but Theo has been spectacular this season. Theo I think got alot of criticism because all he could do was run really fast, but I think he is starting to become more focused on scoring through other options. At the end of the season for Arsenal last year he started to break through, however, he is very injury-proned and almost never gets chances to prove himself. He had a hattrick earlier this season, then next game he got injured for like 1-2 months.
