The 25-year-old attacker has played down his ability despite an impressive start to his second stint with the Bianconeri following his summer return
Giovinco scored twice in the 4-1 win over Udinese on Sunday, and has impressed with his overall performances since returning to Juve from Parma this summer.
However, the 25-year-old believes there is still plenty of room for improvement.
"Am I a top player? I never thought of myself as one, to tell you the truth," he told Corriere dello Sport,
"I must learn to be more confident in front of goal."
After loan spells at Empoli and Parma, as well as being sold to the Gialloblu in 2011, the Bianconeri repurchased 50 per cent of the player's rights for €11 million [£8.7m] this summer.
