If the Juventus staff decide to go with a player already on the roster, it would be Nicola Leali.
Leali is a promising young prospect with a lot of potential, but at this stage in his career he's little more then that.
While at Brescia, he was one of the most sought-after prospects at his position, and Juventus were lucky to emerge victorious from the Leali sweepstakes.
Every young Italian stopper who shows a little promise is called "The New Buffon" these days, but when Buffon was at Leali's age, he was already the full-time starter for Parma and well on his way to becoming the dominant player we know today.
Nonetheless, the potential is there for Leali. He has good size, surprising vision for such a young player and does an excellent job at commanding his area. His reflexes are top notch, and he's been doing a good job of correcting his flaws while on loan at Lanciano.
Six months ago, he had a lot of problems with the way he punched out shots. At the highest level, it isn't enough to just stop a shot; you have to make sure you take away the opportunity for strikers to jump on the rebound.
But Leali has been doing a nice job of working on this facet of his game, and if you take a good look at the video, you can see he does a nice job of limiting the opportunities the opposing strikers get.
Leali is a nice long-term project who could be ready to start for Juventus by the time Buffon decides to hang up his boots, provided he can continue his development.
