David Trezeguet's impending departure from Juventus has concerned his coach of his commitment.

The Juve hitman had previously announced that the 2009/10 campaign would be his last season with ‘The Old Lady', but will not leave till season-end.

Juve boss Ciro Ferrara has confidence that the 31-year-old will keep to his word, but with next June's summer transfer window around the corner, Ferrara still needs reassurance.

Speaking to Sport.it, Ferrara said: "Trezegeut will not betray us.

"Again, I will definitely discuss things with him soon, but he will remain with us until the end of the season."

Trezeguet has been mainly linked to his former side Monaco.
