There is a simple way to throw the onus back on Arsenal and bog this whole thing down.
Based on Van Persie's personal comments, and the sanctioning/airing of them on Arsenal website.
Our lawyers should be on to this very quick and sue for 'Defamation of Character'
After all, it will be up to Arsenal and Van Persie to prove otherwise with regards intent.
All they have managed to air in the public domain so far, is denegrate Adebayor as a person and as a professional footballer, and provide a guilty agenda for those who want to hear it.
There is absolutely no way an FA decision can be meted out with regards 'intent' only on dangerous play (only forcing Ade into a lie detector test would achieve otherwise)
A retraction should at the very least be demanded from the Arsenal end. There are also ground for subjudicy, with regards additional reporting and comment ahead of any FA hearing.
There is a legal argument to be won, even in terms of the PR was which is now being waged.
