By the numbers: Wilshere, Sanchez the difference in win vs. Palace

Arsenal travelled to south London to face a Crystal Palace side that hasn't tasted defeat in eight matches, and the Gunners scored a trio to cement just their third away league victory of the season Thursday.

Alexis Sanchez scored his first brace of the campaign and Jack Wilshere was at his best, marauding the midfield with purpose while stringing incisive passes to the front-three - including a deft long ball that the Chilean corralled for the eventual match-winner in a 3-2 victory.

The Gunners still can't defend under pressure, and there will be questions about man marking in the area on James Tomkins' 89th-minute header, but as Arsenal heads back to Islington, the focus will deservedly be on Sanchez and Wilshere.

Here's a slew of statistics that speak to the influence of Sanchez and Wilshere on Thursday at Selhurst Park.

4: With two goals in a four-minute window, Sanchez recorded his first brace since he scored a pair for Chile against Panama on June 15.

5: Sanchez's five successful dribbles were the most any player registered, two more than Wilfried Zaha.

6 in 9: After an uncharacteristically slow start, Sanchez now has six goals in his last nine league matches.

7: The seven fouls Wilshere suffered were the most of any player on either side.

9: On nine occasions, Wilshere won possession, more than any player on the pitch.

13 in 15: The tireless Chilean has had a hand in 13 goals in his last 15 Premier League London derbies (10 goals, three assists).

26: Sanchez's 26 goal involvements (19 goals, seven assists) away from home are joint best with Harry Kane (22, 4) since the start of last season.

93.7: Wilshere led all players with 93.7 percent pass completion.

120: Arsenal has now won 120 Premier League London derbies, more than any other side.
