Understoood, I think that's a bit of an awkward one for Brighton, how do you replace a keeper for 1 month?
What if the month in question was January, and you had on your books a massively highly-rated, 6'5" England U21 keeper, who was being sent out on loan to the Championship for the season, but could potentially be recalled on the first day of the January window, then returned to his loan club on the 31st...?
