The main issue I have with the 'I am Vito Mannone' chant is the next line - surely there's plenty of people you'd rather be than the Arsenal substitute 'keeper. If not there should be. I'd rather be Wojciech Szczesny for a start.
James Ellis also says: "The song Arsenal fans are trying to get going is "I am vito mannone!!!" to the chesney hawkes number I am the one and only." Thanks James, it could be better though. In my opinion the Emirates faithful clearly need to check out the Roy Orbison smash hit.
