Arsenal boss Arsene Wenger was satisfied with their victory over FA Cup opponents Burnley.
Francis Coquelin made his first appearance for Arsenal since November after an injury lay-off while new signing Mohamed Elneny was handed his debut.
In total, Wenger made nine changes to the side which suffered a disappointing 1-0 defeat against Chelsea in the Barclays Premier League here last Sunday.
"At the start it looked like it would be easy because we had a lot of the ball and good opportunities around the box," Wenger said.
"When it came back to 1-1 it was a different game. I think we were shocked and they gained belief.
"I saw them in their win against Derby and I could see that they were very efficient, a strong team, no weakness, and they have shown that today.
"In the second half I don't think they created a lot, but we managed to win the game and we looked in control in the end."
