Arsene Wenger hailed Olivier Giroud's goalscoring return on Saturday midday as the France international came off the bench to score a brace for the Gunners. Giroud's first two touches landed in the back of the Sunderland net in the second half after Jermain Defoe's spot-kick cancelled out Alexis Sanchez's opener at the Stadium of Light. Sanchez later scored the fourth to seal Arsenal's fifth win in six league matches. However, following the triumph Wenger told Sky Sports: "I would have signed for 2-1 in that time, but the last 10 minutes were relaxing.
"The first two balls Giroud touched were goals. With a player like him on the bench, it's easy to make decisions. "When they score goals you have no headache. But we play every three days, so nobody can play all the games and it's up to me to find the right balance between attacking and defending in every game. "He's a guy who has gone through some difficult times, he was even questioned by the crowd before the European Championship in France. But in the end everyone is on his side." Wenger continued: "I'm happy with the performance, the result. We were questioned with our spirit at one stage because we missed some chances, and at 1-1 you think that you could lose a game that should be over. "We kept going again and won in a comfortable way in the end. It was important to win because we had six wins and then one draw at home, which was disappointing. "To have another game without a win would have maybe created some uncertainty so it was important to win again.
"We wanted not to let them gain confidence. It was important for us to dominate the game and that's what we did."
