As per the report, Arsenal reached the €50m asking price by putting up a deal worth €40m (£34m/$44m) plus €10m (£8m/$11m) add-ons. This isn't something that Bologna are ready to accept and they are looking to increase the fixed sum and lower the add-ons in the deal. At the same time, Bologna are also looking to include a sell-on clause in the deal, something Calafiori’s former club, Basel, did. They retain a percentage between 40-50 per cent of Calafiori’s next sale.
