Looking at Swindon last year, Lampart got banned by polish team, Wajknecht retired, Musielak was (temporarily) injured, Nielsen was (temporarily) injured!
Since they brought Musielak back when he was fit but didn't bring Nielsen back - should that count as a transfer? Otherwise what's to stop a team using a free "injury transfer" for someone who may only be out for two weeks?
Also have they decided how "retired / banned / withholding services" affects these transfer options?
