Arsenal captain Cesc Fabregas insists he is not going to get carried away by his team's impressive start to the new season.
Since drawing at Liverpool on the opening weekend of the campaign, Arsenal have reeled off four straight wins in all competitions.
The Gunners have thrashed Blackpool and Bolton at home in the Premier League and also rattled six goals past Braga in the UEFA Champions League on Wednesday evening.
The next test is a trip to Sunderland, where Arsenal lost last season, and Fabregas is looking to build on a win over Blackburn Rovers in their previous away game.
"I am not going to read too much into our beating both Blackburn and Bolton - in previous years we might have done the same thing before collapsing against the big sides, so it's best that we just keep going, keep improving and keep making things difficult for whoever we face," the Arsenal captain said.
"On Saturday, that will be Sunderland, which is always a very difficult place to go.
"Last season we didn't do well at the Stadium of Light, but it was straight after an international break and we were perhaps a bit tired, so we hope for better this time."
Fabregas continued: "We are happy with 10 points from four Premier League games.
"We would have preferred 12, but we are up there, we are second, and now we need to guard against losing more points because we will need everything we can get at the end of the season."
Left-back Gael Clichy, who echoed his skipper's comments, maintains this time the Gunners must show their true championship credentials.
"We know how difficult the Premier League is so we have to recover quick because we know Saturday will be a battle," he said.
"They are good at home and we just want to show that we can perform week in week out."
