Arsenal boss Arsene Wenger marvelled at the standing ovation the Portsmouth fans gave his side after the Gunners' crushing FA Cup win at Fratton Park.
"The result is wonderful," he said. "But it is even more enjoyable to see opposition fans cheering our team.
"Our game was really fluent. Our passing and movement gave Portsmouth many problems.
"And of course, we took our chances. Overall I'm very pleased with the way we played and our sharpness.
"We were able to keep our concentration over 90 minutes and our attitude showed that we want to stick to the quality of our game.
"When confidence is high like this, the players really enjoy it."
Thierry Henry's brace was also welcomed by the Gunners boss, who thinks his striker is firing on all cylinders again.
"He looked a bit tired a couple of weeks ago," Wenger added. "But now he's back at his top form once again.
"I noticed it coming back in training and he has obviously benefited from the rest he had."
