Monza chief Angelo Sticchi Damiani has confirmed that negotiations over the details of a new Formula 1 race contract are now taking place.
It was reported on Tuesday that, after a long period of fraught negotiations with Bernie Ecclestone, officials had finally shaken hands on a deal with the F1 supremo in Monaco last weekend.
Sky Sport Italia had said that a contract for the period 2017 to 2020 will now be drafted.
Sticchi Damiani, the president of the Italian automobile club (Aci), confirmed to La Gazzetta dello Sport that Monza promoter Sias is negotiating with Ecclestone about "a contract of four instead of seven years".
The 2016 championship continues with the Canadian Grand Prix on June 12.
