I can see where you are coming from . I agree it was a mistake to take out Campbell who is playing so well instead of walcott who has been so awfull . But we needed a goal and Walcott is more likely to score in a big game than Campbell who has yet to score in a big game for us . Another thing , we created a few chances but didn't take them away . Was that Wenger's fault as well ? I am not defending him at all but I want us to reflect on the game with no emotion .
