ESPN FC's Craig Burley says Arsenal completely controlled proceedings against a somewhat lacklustre Chelsea side. As you're no doubt aware, Arsenal managed to actually beat Chelsea for the first time in what feels like decades, romping to a comprehensive 3-0 win at the Emirates Stadium on Saturday evening. A quick blitz of first-half goals was enough to secure Arsene Wenger his first league win against the Blues since way back in October of 2011. In the direct aftermath of the game, Theo Walcott -- who scored the Gunners' second goal -- marked the result by posting a celebratory image on his Twitter account.
