Laurent Koscielny believes Arsenal failed to take full points against PSG as they dropped off after scoring the second goal, allowing the visitors to pile on the pressure and eventually equalise through Lucas Moura. The 2-2 draw means that PSG are currently top of the group owing to the away goals rule, with the Gunners having drawn the Parisians 1-1 in the reverse fixture.
A win for PSG against Ludogorets will seal their fate at the top of the group, while the Gunners have to hope that the Parisians falter and they are able to take full points when they travel to Switzerland to take on Basel. The north London club have not progressed out of the group stages in the last six seasons and would make it very difficult for themselves if they finish second in the group yet again.
Edinson Cavani opened the scoring for the visitors with a well taken finish from a through ball by Blaise Matuidi and the visitors were the dominant team before Alexis Sanchez was deemed to have been fouled inside the box. Olivier Giroud equalised for the Gunners and the hosts took the lead following an own goal by PSG's Marco Verratti. The scores were levelled again as Moura's header deflected off Alex Iwobi into the back of the net.
"We tried to win but we conceded the second goal and I think that killed us," Koscielny told Arsenal's official website. "We pressed hard in the last 10 minutes of the first half and first 15 or 20 minutes of the second half, and they were in trouble because they lost so many balls in their own half.
"We were able to create danger in their own half so it was better for us to press high, but after the second goal we stopped pressing and dropped a little bit. We gave them lots of opportunities which is why we conceded the corner and then conceded the goal."
