Arsenal goalkeeper Petr Cech says his team could've played all night and not scored against BATE Borisov.
The Gunners will need to overturn a deficit to advance to the Europa League last-16 after BATE handed them a stunning 1-0 defeat in Belarus.
Cech said: "Yesterday it was one of those games where if we played for another couple of hours probably we wouldn't have scored. But there are games in football like that.
"You try, you play, the goal does not arrive and you have to go home with the result you don't want but you have to pick yourself up and be ready for the second leg. This is the advantage of playing two-legged ties – when one game goes wrong you can always make up for it."
