Top 5 All-Time $uper M€ga Cra$hing Tran$fer F£op$

Sorry for the overnight delay, I was attacked by the headache monster and dozed off earlier than planned without finishing. I'm back to rip five new ones in a historical context. Granted, the explosion in transfer fees during this decade means this T5L won't be overly historical - the earliest transaction here occurred in the summer of 1998.
