Alex Song insists Arsenal must be on their guard in their UEFA Champions League opener against Standard Liege.
The Gunners travel to Belgium on the back of two Premier League defeats after losing away matches to rivals Manchester United and City.
Chelsea and the Red Devils both won their Champions League openers on Tuesday and Cameroon international Song insists Arsene Wenger's side must follow suit.
The midfielder acknowledges spirits in the camp are down and that getting back to winning ways in Belgium will help restore confidence and self-belief.
Liverpool made hard work of the Belgian outfit last season before Everton were undone in the Uefa Cup and Song knows Laszlo Boloni's side will be no pushovers, particularly on home soil.
"We need to start well in the Champions League," he told skysports.com. "A good start brings assurance and confidence to the team.
"We've lost our last two games when we've played very well. Standard are a good club. They're a top team in Belgium and gave Liverpool a decent game last season.
"They almost beat Liverpool at Anfield. I think (Jose) Reina saved a penalty in their game, so they are good. We need to play and be positive. We have to get something from the game, it's simple as that.
"We lost against City and Manchester United but that's football. We have to make sure we go on an unbeaten run like 12 games. To win leagues or trophies you have to go on an unbeaten run."
