Are you able to sign free players?

I've won 3 auctions today, 3 free players. I've got my tokens back, but don't got the players. I've submitted a ticket. It was strange, because I haven't seen free, young, sellable players in the market for about 5-6 seasons. I'm level 34, need the money, because of the known issues at higher levels.

I only took a screenshot from the lastone:
