Barton punched someone without provocation for a laugh, mate.
Punching someone in the chest is nowhere near as cowardly an act as elbowing them in the face as the run alongside you.
Eh? That has absolutely no relevance whatsoever to what i've just said.
It's about as relevant as your comment in response to what Nixon said.
Which is easier to understand, seriously? 'Understandable' is the word he used.
We all know why Coloccini elbowed Elmander, his opponent got the better of him and he cowardly lashed out to avoid being beaten again. None of us have a clue why Barton decided to punch MGP. It could have been boredom, for all we know.
