Walcott arrives on the scene - Jan. 20, 2006

Cup misery - Feb. 25, 2007

First league goals overshadowed - Feb. 23, 2008

That shows that he improves."
Comeback kid - Feb. 26, 2011
Walcott helps Arsenal stage a remarkable comeback in a memorable North London derby as the team rallies from 2-0 down to beat Tottenham 5-2 at the Emirates Stadium. Walcott has a bad start to the game and is jeered by parts of the frustrated crowd in the first half, but recovers to score the last two goals in a three-minute span in the second half to send the stadium into rapture. Wenger reveals: "I was scared for him because he missed some controls and some passes and people got on his back, but I felt that he could come back into the game."
Last gasp goals - Oct. 30, 2012

Trophy winner - May 30, 2015
After being used sparingly by Wenger since returning from his injury, Walcott is chosen ahead of Olivier Giroud as the starting striker in the FA Cup final against Aston Villa at Wembley.
