Arsenal boss Arsene Wenger says Olivier Giroud's opener against Swansea City allowed his team to dominate the game and ease past the hosts at the Liberty Stadium.
The Gunners continued with their impressive moment of form in the English Premier League as they kept their second position - on goal average - in the table.
And the Frenchman was also pleased with yet another clean sheet by goalkeeper Petr Cech.
"It is always a difficult game, we were a bit edgy [in the first half] but in fairness Swansea showed quality again today," Wenger told reporters.
"They are maybe going through a spell where they have less confidence but they are a good side. In the first half, it was difficult but in the second half we upped our purpose, our tempo and had more purpose in our passing, with pace in our combinations.
"Once we scored the first goal we were the dominant team and won the game normally.
"We had a difficult first half but we came through it. I rested eight players on Wednesday and gave them a little breather this week, and it took us a little while to get into the tempo of the game.
"I am pleased because we could keep a clean sheet during the difficult moments of the game and you are never in a hurry to take too many risks going forward. Once we scored the first goal it was a completely different game."
