Arsenal defender Bacary Sagna is determined that Arsenal will put their troubles against Standard Liege behind them, making them a stronger team in the Champions League this season.
The Gunners trailed 2-0 in Belgium after only five minutes but came back very strongly to win 3-2. And now Sagna insists the team will learn from their mistakes and bag back-to-back victories against an Olympiakos side which has never fared better than a two-goal loss on English soil.
And Sagna thinks the best form of attack will be defence.
"I hope everyone is ready now to give 100% on the pitch, including the forwards because they are the first to defend,'' the French full-back said. "Everyone knows we have to be more powerful in defence to be good in attack.
"We have a good team and everyone is able in this team to play good football and we show it.''
