Arsene Wenger savoured Arsenal's finest performance of the season after Porto were crushed 4-0 in the Champions League on Tuesday night.
The rout dispelled the gloom that had descended over the Emirates Stadium since Saturday's humbling defeat by Barclays Premier League newcomers Hull. Robin van Persie registered his first goals in European competition for a year when he fired a well-taken brace while Emmanuel Adebayor also scored twice.
"The most important thing was to respond quickly in a convincing way to the game against Hull and that's what we did," Wenger said.
"We were focused and I was happy with the attitude," he added. "Maybe we were too tense at the start of the game but we were focused and at this level that is vital.
"It's difficult to measure our best performance of the season but this was maybe our most complete performance. This is half the response I want. The other half comes on Saturday against Sunderland. I expect to win the group after this."
Wenger was delighted with the contribution of Cesc Fabregas and Theo Walcott, who caught the eye with a string of marauding runs down the right wing.
"I thought Fabregas was outstanding. He was good offensively and defensively. It was a complete performance," Wenger said.
"Theo was dangerous again and is always improving."
Wenger had threatened to overhaul his team in response to the defeat by Hull, but in the end just replaced Emmanuel Eboue with Samir Nasri.
"I was tempted to make more than one change but I didn't want to give the feeling that I was punishing one player more than another," he said. "I wanted to give the team the chance to respond quickly. The change was not to punish anyone, it was because we needed to respond quickly as a team."
