Juventus are on red alert with news of Bosman signing Fernando Llorente suffering a serious knee injury.

The Athletic Bilbao centre-forward agreed Bosman terms with Juve last week and will move to Turin in June.

However, Sportmediaset says alarm bells are ringing inside the Juve boardroom after news that Llorente has broken down with a major knee injury.

Bilbao announced Llorente had suffered a "sprained right knee" and he will undergo a scan today to assess the extent of the problem. There are concerns of ligament damage.
