Arsenal defender Koscielny: Champions League qualifier will be crucial
Koscielny hopes his team can take confidence into the new campaign, which will see them play a crucial Champions League qualifier in August.
"The second leg of the Champions League against Bayern Munich was a trigger for us," he said. "In the process, we almost won everything.
