You can follow all the drama of Deadline Day with Sky Sports - and to help we've created a fun A-Z glossary of some key words, names and phrases for the big day.
The 2018 January transfer window will close at 11pm on Wednesday, January 31 and there will be coverage throughout the day on Sky Sports News and Sky Sports' digital platforms.
If you're on the move, you can keep up to date with the Transfer Centre, where our rolling live blog features the latest news, views and analysis.
But make sure you keep our Deadline Day glossary handy...
