Arsenal midfielder Alex Oxlade-Chamberlain says they must not ease off in the Champions League against Anderlecht.
Oxlade-Chamberlain believes Arsenal can use that momentum for their trip to the Belgian capital, where they will be without goalkeeper Wojciech Szczesny following his red card in Turkey.
"We are going to go there and we know we need to back up our performance (against Galatasaray)," he said.
"We knew after the Dortmund game that we weren't good enough that night, so we knew we had to put things right.
"It is important we don't take our foot off the gas now. We need to go to Anderlecht and hopefully get another three points."
