It depends how much money do you have for transfer. I remember I managed 1860 at second division and signed Arne Friedrich, a great defender on a free transfer. There are plenty of good players for loan, especially wingers, on the first division sub 23 teams. If you are looking for a good free transfers, try to bargain the high wage player(but high quality ones tho) Markus Proll and you can sign the realiable defensive full back Volz for free as well, most of times they will accepted a 0 offer for him.
