Juventus boss Massimiliano Allegri doesn't doubt Carlos Tevez's commitment.

Tevez struck in victory over Lazio yesterday amid fresh talk of a return to Boca Juniors.

Allegri said: "It's natural to feel nostalgic for home, friends and family. We all do, let alone him being on the other side of the world.

"Tevez is proving in the best way how focused he is on Juventus."
