It reads: "Subject to the provisions of Rule V.1, the deadline for receipt by the board of all duly completed documents required by these rules to effect the registration of a player shall be 12 noon on the last working day before the date of the first league match in which the club making the application intends him to play."

It continues: "Save that the international transfer certificate and evidence of eligibility to take up employment in the United Kingdom (in both cases if applicable) may be provided thereafter (but must be provided before the player is eligible to play for a club in a league match)."Despite speculation linking Gravenberch with a move, Jurgen Klopp was reluctant to confirm the transfer in his press conference on Friday morning.
