Juventus coach Max Allegri says Dusan Vlahovic retains his confidence.

The striker admits he was disappointed starting victory on the bench against Frosinone.

Allegri said: “He had played three good games, but he had been criticised, so he needed to self-soothe.

“He could give us great help in the final minutes.

"He knows he has to improve, especially at a mental level and he played well when he was introduced."
