Newcastle United new signing Sandro Tonali's deal does include the option of another year.
The Magpies have secured the former AC Milan midfielder on a five-year contract.
However, Chronicle Live states that Newcastle can tie Tonali down to a sixth year if they wish.
If he is sold, Milan will earn 10% of any future fees that Newcastle pick up from other clubs.
The fee for Tonali is set at around 60 million, with the midfielder yet to pick his shirt number.
While he wore no.8 at Milan, Anthony Gordon already has the number, which means the no.6 may be an option.
