"It's not good enough, and you can't play with this mentality," said one of Arsenal's standout performers from their 4-2 victory over Leicester City. It was Granit Xhaka that said those words, but he wasn't moaning about this impressive victory, it was just over two years ago in a loss away to Aston Villa.
It was a time during which the Gunners had their weak mental state criticised by fans, pundits and also their own managers. There was a general acceptance that from the later years of Arsene Wenger's reign at the Emirates, Arsenal had become somewhat a pushover and no longer a team for the big moments. It's too early to say that it has completely changed, especially after the collapse towards the end of last season, but a lot has changed since then.
Mikel Arteta's transfer activities have added eight Premier League titles to the squad and a vast array of experience from situations that not only are Arsenal not used to being in, but they also haven't been there consistently to properly learn. But that looks set to change.
