Hyperion_20: "I'm very proud of the way the team played and we won deservedly. I couldn't have hoped for a better display - our defence was rock solid, the midfield played the ball around well and Rooney did his best despite the penalty miss."
Super Saiyan4 Goku: "I felt we controlled the game and Rooney looks to be getting sharper. Shame we couldn't have taken more chances, but hopefully we'll be more clinical against Chelsea."
ProfessorUnited: "A great team performance. Who says we have problem in defence?! We played as a strong unit and Wenger as usual had no plan B. He was once again tactically outfoxed by the master."
DR08: "We did great to grind out that win. Everyone played well. Great effort by our attackers for constatly pressing and providing cover for the defenders. Park was Man of the Match for me, not just because he scored the winner, but he covered so much ground and did a good job at both ends."
Man-Utd-Fan: "We are now in our rightful place at the top of the table."
maithem: "Great win. Let's hope for more good news next weekend with a win at Chelsea."
