Olivier Giroud came on to score twice for Arsenal against Sunderland, and manager Arsene Wenger was thrilled with his impact.
Arsene Wenger was delighted with Olivier Giroud's goalscoring return on Saturday as he came off the bench to help fire Arsenal to a 4-1 victory over Sunderland.
The France international scored with his first two touches of the ball after replacing Alex Iwobi in the 69th minute to put the Gunners 3-1 ahead after Jermain Defoe's penalty had cancelled out Alexis Sanchez's opener.
Sanchez added a fourth in the closing stages as Arsenal cruised to a fifth win in six Premier League games to go temporarily top of the table.
