@Zachary Whyte I have uploaded a file to ownCloud with the name "James Render - sc Heerenveen 2025.12.27pre-transfer.fm" which is a couple of days before the window opens.
Agreed a loan move for a player, with a buy option. He then joins the club and I trigger the buy option (to come into effect in the summer). But he is now unavailable to play because he would then become ineligible to play for his new club, which would be me.
