Hello,
I selected the players for an IS match yesterday.
The match took place at 6pm, so I selected the players at 1pm. They were supposed to return to their clubs at 9pm. They're still with me this morning.
How come? Could you send them back to their club?
Thank you for your help,

You had a friendly scheduled while the players were still in your squad, so their loan was extended because no player can leave the club during a match (except on loan to the federation).

Thanks for the feedback, I hadn't realised how it worked. That makes sense :-)
thanks!
