During the second game of the friendly competition, which consists of three 45-minute matches, reigning Serie A champions Juve triumphed 1-0 over AC Milan.

Caceres has reportedly suffered knee ligament damage, but Juve coach Antonio Conte said he was unaware of the extent of the injury, and played down a knock to Mirko Vucinic.

"Vucinic only had cramp, but Pepe had a thigh strain, and we don't know about Caceres yet," Conte said.

The Juve coach was critical of the pitch at Bari's Stadio San Nicola, blaming the surface for the injuries suffered by his players.

"It's a shame that such a wonderful tournament watched by so many people is played on a pitch that does not help football and makes injuries more likely," he said.

"Tonight we face important sides. Despite the introduction of new faces and many absences, we are working hard so everyone can understand the concept of our football.

"I saw positive aspects, but we know that there is a long way to go and we will grow. The defence did well. Lucio has to learn to improve his movement, but is at our disposal and will be strong for our team."
