For me it has to be Gabriel Batistuta, that would have been legendary! http://www.thisislondon.co.uk/sport/charlton-no-to-batistuta-6352045.html
Wow- never knew about batistuta. That would have been amazing. This also just reminded me that we rejected Rivaldo last November. I assume he's past his best, but I would definitely have had his name put on my shirt.
