You have the grace period. But Nordeus will probably gave you the retiring 2-3* players for you...Please renew now or you'll have them. They can't be sold or renewed. You'll have to waste extra money sacking him too...
noope, you dont waste money sacking overage players they give you. it costs ZERO $$$ to sack them.
Wait until the first day of the season to re-sign the players you want to keep as they are up to 15% cheaper to sign and you get a full 3 year contract.
