To be fair, he is like any other senior successful professional in any other industry...there is always demand for someone of that profile and people in regular industries can't stop either and work on till their 70's
Bring him back to Juve as backup to get that coveted CL trophy. Would be fitting end to an iconic career. What a motivation boost I believe for the entire club to have him around. Gigi won't want big money and if you gave Sami 6 mil, Agnelli be smart and do it!!!
