Alexis Sanchez and Olivier Giroud both hit braces as Arsenal moved to the top of the Premier League table with a 4-1 victory over Sunderland at the Stadium of Light.
Sanchez and Giroud's goals mean the Gunners edge three points ahead of Manchester City -- who play West Brom later on Saturday -- at the division's summit and have stretched their unbeaten run in all competitions to 14 matches.
In contrast, the defeat for Sunderland leaves them rooted to the bottom of the table, while they have now had the joint-worst start to a season in Premier League history over the first 10 games, with their tally of two points equalling Manchester City's haul in the 1995-96 campaign.
