Today always promised to provide plenty of talking points and nowhere more so than at the Etihad in the big match between Manchester City and Arsenal.It's the Gunners who are currently showing they are the team to rival Chelsea for the title and are 45 minutes away from going 2nd in the Premier League table.That's thanks to Theo Walcott who sensationally put his side 1-0 up within 5 minutes to send the away end into raptures. It's a lead Wenger's side have held going into the break.The delight, of course, was felt by Arsenal fans all around the world and thousands have taken to Twitter to show their love for Walcott, who is having one of his best seasons in an Arsenal shirt.That goal was his 11th of the season. Quite the turnaround in his Arsenal form, obviously enjoying the link-up with Sanchez and Ozil. It was Sanchez who supplied the English attacker with a beautiful pass to set up the chance to finish.Can the Gunners put in a second half performance worthy of the first or can Guardiola prove to Man City fans his team selection, panned before kick-off, was justified?
