Between recruiting, managing finances, developing tactics, handling the media and dealing with a bunch of insecure whiny cry-babies it's an unpaid, full time job.
Portsmouth currently, wage budget, seems to be my main stumbling block, transfer budget for my 3rd season (3.7M in championship). Really satisfying finding a player for nothing and him playing well for you. most fun ive had with a save since i dont know when.
Club Brugge in FM14 definitely. Had this regen called Vincent Coulon who I got for free from Basel. In FM15, Millwall. Got them to BPL and a 10th place finish in the BPL in 2 seasons.
