Transfer deadline day brings the worst out of clubs. Not wanting to be left behind, desperation sets in and it all makes for spectacular viewing – especially in January.
Today's deadline day is already shaping up to be one of the best in recent memory.

So with the window closing in less than nine hours, we've looked back over the 15-year history of the January transfer deadline to remember five of the biggest deals ever struck on the final day of the window.
Some were successes and some were not. But they all made for dramatic finales.
