http://www.football-rumours.co.uk/ is full of teh lulz.

i love a rumour, i do, especially when any sensible person knows it's 100% fabrication.

i particularly likes these:

Arsenal Transfers ( FACT )
Players in:-

A young skillful player– 2 million

:)

Several rumours i have heard from some good sources are:
Michael Owen to Celtic

:D

Liverpool signings as follows:

Wesley Sneijder + Sergio Ramos (10mil + Alonso)

pick your favourite! or tell us about an outrageous rumour you've heard recently.

Cheers.
