What are the rules?

Here are the relevant extracts from the official competition regulations:

• 44.01 For all matches from the start of the round of 16, a club may register a maximum of three new eligible players for the remaining matches in the current competition. Such registration must be completed by 1 February 2018 (24.00CET) at the latest. This deadline cannot be extended.

• 44.02 One player from the above quota of three who has been fielded in a UEFA club competition group stage match for another club in the current season may exceptionally be registered, provided that the player has not been fielded:
  a. in the same competition for another club; or
  b. for another club that is currently in the same competition.
