There is no answer to that question, as Arsenal are not out of the Champions League yet, despite an awful defeat in Zagreb.
To make matters worse, Giroud got himself sent off for a clumsy challenge after seeing yellow for dissent. Well, at least the game mattered to him.
As for Wenger, I felt he underestimated the opposition: he fielded a side that shows he had one eye on the Chelsea. Now that's not necessary a bad thing: he's only prioritising the league.
As Wenger said afterwards, he's confident of beating Zagreb at the Emirates. However, he'll have to field a stronger side if he aims to do that, as Arteta seems a pale shadow of his former self. Without Coquelin, in fact, the whole team seems to suffer.
At least, Walcott proved how good he is in one-on-one situations. Now he needs to start scoring some tap-ins to make sure he gets a healthy goal return. And as Wrighty said on TV, he should get the run of games that he needs upfront after Giroud's indiscipline.
