If sale of Thiago Silva and Ibra go through Milan will be saving ~30-32.5m per year on wage costs. That's counting in saves made on players who have left on free ( Gattuso, MVB and so on ) , players who have signed new reduced contracts ( Flamini, Ambrosini ) and also estimate of money paid to new players who have joined ( Montolivo,Acerbi,Traore )
This is not yet counting probable sale of Taiwo and loan of Mesbah, but those dont make big difference as they were on quite low salaries already.
By these calculations I think Milan's wage to revenue ratio is now closer to 70 when it used to be almost 90%. Far from healthy, but much better than other big italian clubs have.
