Juventus president Jean-Claude Blanc is battling to keep hold of his job.

Sportmediaset says there is a growing rift between patron John Elkann and Blanc over the club's on-field demise this season.

The Frenchman's decision to return home last weekend as Juve were being thrashed by Udinese has infuriated Elkann.

In Blanc's favour, however, is Juve's success bringing in new sponsorship and also having their new stadium plans on track and within budget. But on the field, Juve's struggles are working against the Frenchman.
