Juventus coach Max Allegri sung the praises of Federico Gatti after victory over Europa League opponents Sporting CP.
Gatti proved the matchwinner for the 1-0 quarterfinal first-leg triumph.
Allegri said of the defender: “It is not an easy season for us, young lads need time to grow.
"At times they can look fantastic, at others like they've never played football, it is a whole different pressure playing for Juventus.
"Gatti has so much energy and is like a sponge, he soaks up all the information you throw at him."
