Inter Milan chief Michael Bolingbroke admits their relationship with Pirelli could be coming to an end.
Bolingbroke was speaking to Inter shareholders.
"In June we'll celebrate 20 years with Pirelli as a partner and as far as I know it's the longest partnership in football history," Bolingbroke said.
"Not even the one between Liverpool and Carlsberg lasted as long as this.
"It seems impossible to imagine ourselves without Pirelli, but everything comes to an end.
"We are currently negotiating with them in order to understand what to do. In a commercial partnership both parties must take advantage.
"We are not talking about money but rather advantages that we could bring to Pirelli through our project."
