Watch Arsene Wenger 's Sunderland 1-4 Arsenal post-match press conference in full, in the video above.
Arsenal headed into the lunchtime kick-off on Saturday knowing three points would put them top of the table - and they took their opportunity.
Alexis Sanchez put the Gunners ahead with a neat header after 19 minutes, but the Gunners were pegged back through a Jermaine Defoe penalty just after the hour mark.
Wenger decided to change things up by bringing on Olivier Giroud , who, back from injury, made an immediate impact.
The Frenchman scored twice with his first two touches to put the game all but beyond doubt.
Alexis Sanchez made sure of the victory in the 78th minute using neat footwork to get his second.
Speaking after the game (as seen in the video above), Wenger stated he was happy his side managed to dictate the game.
Asked on Giroud and Ramsey's return, Wenger said he was pleased with the depth of his squad.
The Gunners boss also admitted to now having a selection headache with the return of Giroud.
