I have found something, dont know If it works the same way on all server.
Like you i have now one team with the New transfer market, so i have been watching it all day more or less.
It seems that in my server they are showned all at the same time more or less at the same hour, all with less that 10 minutes until the end of auction.
In the morning they appeared at 10:14
In the afternoon 15:16, 16:19, 17:06, 18:07
It cant be a coincidence!
