I remember at the time it felt like Allardyce needed more time to get things to click. Wasn't sad to see him go as such as I wasn't happy about him signing in the first place, I remember feeling like he hadn't been given much of a chance.
That said, I always favour giving managers that little bit more time.
In retrospect his legacy is mediocre, at best. His record since being sacked has vindicated Ashley & co, if we're being honest.
