Who is trying to sink his confidence? He had 1 goal in 12 games before Auba was brought in. No one on Arsenal played particularly well today, and Auba would have had the most dangerous chance if not wrongly called offside.
Instead of blindly defending a french player, just admit that he's not playing well at the moment. And he is to blame for much of it, not everyone else.
I don't have a problem saying he's playing poorly. But him being in a dangerous position is already better than the rest of the team.
And yes, I don't know if you've followed Arsenal, but Wenger did all he could to sink Lacazette's confidence, from the get-go.
When he was scoring, he was still benched.
Even though the stats prove that when Ozil, Alexis and Lacazette were playing together, Arsenan were never losing (with the exception of the United game, that Arsenal totally dominated).
But hell yeah. Let's say he sucks. Let's call it La Baguette. Or other arguments that show a level of maturity and football knowledge close to zero.
