The Poland international joined the Old Lady over the summer window and is seen as the new long-term replacement for the Juve legend Gigi Buffon.
Former Arsenal keeper Szczesny believes he is settling in well at the club and admitted he never had any intention of going anywhere else after he heard of Juve's interest.
“I came here because I need to win everything,” Szczesny told Mediaset Premium.
“I chose Juventus for their winning mindset. Every day in training I feel stronger and more ready to play for this club.
“It seemed a normal choice to me, when Juve call you, you have to go. When you play for Juventus the goal is always to win everything, and it’s no different this year."
