"Over the last few days an important meeting has been taking place between the directors of Juventus and Oilinvest, the company which owns the Tamoil brand, during which the future strategies of the club were illustrated to Juventus? Sole Official Sponsor. Tamoil has agreed to the projects and has confirmed its desire to remain at Juventus? side for the next four years, opening immediate discussions to work out the details of the new deal. At the end of the meeting the companies agreed to the continuity of the partnership, guaranteeing the existing exposure of the Tamoil brand, which will therefore continue to be present on the team shirt, as of the opening game of the championship."
That they want to continue to be our sponsor is good news.They are not only our sponsors, they own several shares. I don't know exactly how many; - somewhere between 7 - 11%? I think the only party with more shares are the Agnelli's. If they had abandoned us, they might have sold the shares & caused the share price to drop, which would have been bad news for Juve.
