Lookin in from the ouside, I like the current one and #1. The others are of a group of players celebrating a major achievment, but are all missing John Terry for some strange reason.
No style in that. Only number 1 has any sort of style but a thank you Sir Alex would be pretty good, the first one UIR posted is decent.
Remember that the banner is very thin, so the first one UIR posted will look very bizarre, probably just showing SAF's eyes like a horror movie poster! Still, it would probably scare a lot of the wums away! The thank you Sir Alex one would probably work better, but we need a larger version (at least 1800 pixels wide) if it's to fit on the site.
