We've taken a look back at Middlesbrough and all their current Championship rivals' most expensive January signing in their respective club histories, and set you the task of naming all twenty players. While their faces may be blurred, you'll be given a clue in the fee, former club, and year of the transfer.
Keep a note of your answers, as all the players will be named on the final slide. Good luck!
