The January transfer window runs from New Year's Day to the end of the month each year. In previous seasons clubs were able to register new players for their knockout stages of their European competitions - but only if those players hadn’t already played in Europe for another side earlier in the season. But UEFA have now scrapped that rule and instead players will be free to represent TWO clubs in Europe either side of the transfer window. To appreciate why this is significant, you only have to look back to the January 2018 transfer window.
