Their defence has declined further defying belief

It seemed impossible to say last season but the Gunners have actually gotten worse defensively.

At least last term they would go two goals behind before they pulled it back.

This season, they take the lead (sometimes quite significantly) and STILL manage to blow it.

Yes, injuries have hampered their defence but a total lack of protection in front of them, not to mention a clueless manager, has made it worse.
