That was the reason for my question to Kincy. The EPL made noises about banning transfers by any clubs using the furlough scheme - 'we can't afford to pay wages for our existing staff, but we'll just spend a lot of money (that we told you we don't have) to bring in another salary commitment'.
No idea whether the SPFL said anything similar or whether HMG might be interested in this.
ETA: this isn't a question specifically aimed at Rangers - the same might apply to all other clubs using furlough, including United. Are transfers moral or legal at the moment?
