Can I sell a player halfway through a matchday?

Yes. Whether they are in the line-up or you have them on the bench, the transfer market never sleeps.

If you opt for the immediate sale of a player who is in your confirmed line-up and their match has still not been played, you will still earn the points that they obtain.

If you opt for the immediate sale of a player who is in your confirmed line-up and their match has already been played, you will not lose the points that they obtained.

If you put a player up for sale who is in your confirmed line-up and complete the transaction before their match is played, you will still earn the points that they obtain.

If you put a player up for sale who is in your line-up and complete the transaction after their match is played, you will not lose the points that they obtained.

During a matchday, the immediate sale or the sale to other users of players not in your line-up will not affect the points of your team or the team that signs the player, and these players will be eligible to enter the line-up of their new team beginning on the next matchday.
