The last time Arsenal beat one of the 'Big Four', they failed to build on it. Arsène Wenger is determined not to let that happen again.

Last month's pulsating 2-1 victory over Manchester United was followed by a convincing win in the Carling Cup but then two defeats in the Premier League. Sunday's comeback at Chelsea has given Arsenal a second chance to reignite their campaign and Wenger wants the Stamford Bridge afterglow to last a lot longer than one game.

The Carling Cup takes centre stage tonight but, in the longer term, Wenger needs his players to maintain their momentum when the Premier League campaign resumes.

"We are cautious because of what happened before [after the win over Manchester United]," Wenger told Arsenal TV Online. "I believe that is where we can show that we have learned and we can keep the temperature up, that is the target of the next game.

"The Premier League is difficult because as soon as you drop a bit off of your level you don’t win. That has changed since five years ago."

Arsenal have come unstuck against some of the top flight's lesser lights this season - Hull City, Stoke City and Fulham all beat Wenger's side before Aston Villa and Manchester City inflicted further damage late last month. Wenger knows that Wigan and Middlesbrough - Arsenal's next opponents - will also dent his team's title challenge given half a chance.

"No matter who you consider you can be in trouble against every single team," said Wenger.

"I would like to take the positives from [Sunday's] game because I believe we have shown character.

"At 1-0 down at Chelsea if you don’t really fight, you have no chance. Very few teams come out with a victory once they are 1-0 down at Chelsea. You could say that Liverpool have won 1-0 and Man United have drawn 1-1 but they were never 1-0 down and you need something special to come back and win the game from that position."
