I think it's an agenda against Liverpool FC. I know every fan of every club will say it, but in this instance, I think Suarez and Liverpool have a case to feel aggrieved.
Why?
There was a precedent set by Jermaine Defoe biting Javier Mascherano in 2006. Martin Jol laughed it off as "comical" at the time. Pardew, the West Ham manager at the time, probably couldn't be bothered to comment.
Why is it that such an incident 7 years later (and let's face it, biting is biting. There isn't really much difference between the scenarios) is played out over and over again on a 24 hour sports TV channel? Is it just because of his reputation? In which case, it's still wrong to continue this 'trial by television' based on the aforementioned precedent.
