Greetings, sir.
Although you said that you own a football site, you didn't mention which one is it, but if it's similar to 442 or worldsoccer, then it must be good.
Well, I would like to suggest to turn some of my remarks into ideas. Football sites usually don't have, or have ultra small amount, humor in their articles. I think I could help in that sphere. They tend to be strictly informative and that's usually it. But putting some quality humor throughout the articles could really inject some fresh blood, smiles and curiosity of your (potential) readers.
Further, maybe it would be good to add up some sections like mentioning some old legendary players and what have they achieved, comparing them in some special fields, make them live once again and let readers be also involved in some way, maybe by voting or simply letting them to express themselves in given situation.
Maybe hire a caricaturist to draw some of those crazy ideas, for example, that goal of Ryan Giggs in '99 against Arsenal. It would be funny and cool to see it done like caricature, faces of defenders, Giggsy's abnormal chest hair etc.
I am a songwriter by the way and I could provide you with some nice and funny lyrics on some given subject regarding some event, player of club, manager etc. There we go, some brainstormed ideas out of nowhere. I really hope you'll like some of these, 'cause they come from passionate football fan.
Best regards to you,
Bojan
