thank you very much for your answer
trainer and young trainer ok, I had a doctor for longtime, level 3, but to be honest, at my level, I was wondering is it is not the best option to buy another player, if one has a long blessure, than paying an high salary. I'm start thinking that staff and structures are just for really top teams, at III or IV div they are totally worthless and money draining for what they give back.
