Juventus coach Ciro Ferrara concedes Diego is unlikely to make their Champions League clash with Bordeaux after suffering a thigh injury in their victory at Lazio.
Ferrara said: We have to wait for tomorrow's results, but if Diego asked to come off then I think he must have something fairly serious, as he usually wants to stay on at all costs.
"He felt this twinge when he changed pace and it was limiting him."
