Arsenal returned to the top of the Premier League on Saturday as they thrashed hosts Swansea City 4-0 at the Liberty Stadium.
Olivier Giroud opened the scoring in the first half before second-half own goals from Jack Cork and Kyle Naughton and an Alexis Sanchez strike sealed the victory.
The hosts failed to capitalise on a lacklustre Gunners' performance in the first half; in the second, Arsenal were far more convincing in the final third and made the Swans pay.
After a slow start, the first chance of the match fell to Naughton as he forced a smart save from Petr Cech with a powerful effort.
