We were naive from the off. Dortmund came with a plan, they got in between the passing lanes and played on the counter-attack. We tried to play too much football (Ramsey tried to play it out of our own box but that can be categorised as an individual mistake). We got to 1-1, sometimes it's better to protect what you have. We could've played a bit more on the counter attack ourselves, but I don't think Dortmund had any intention of doing much with the ball.
Ramsey fucked up, yep.
At the start of the game, Arsenal barely even tried to play football. They were solid, took no risks and let Dortmund have the possession. Which Dortmund are useless at. A mistake by Ramsey changed things.
They could've settled for a draw after Girouds goal, sure but come on, everything in the second half suggested that they were about to score. I don't think it was naive at all. They had everything under control and kept creating chances.
As for counter attacking; They tried it at times, it's difficult when you don't have the players for it. They tried to attack in different manners, by using quick counter attacking moves and by dominating possession. None of them were wrong. They just didn't have the luck that was needed today.
