Inter are hoping to maintain their stay at the top of Serie A when they visit the reigning champions, and the coach admits it is a crucial encounter
Luciano Spalletti believes Saturday's Derby d'Italia clash with Juventus will allow him to judge whether or not Inter have what it takes to compete consistently against the best.
Inter go into the eagerly anticipated meeting top of Serie A, having gone to the summit for the first time since January 2016 with a 5-0 hammering of Chievo last time out.
Their improvement under Spalletti this season has been remarkable, with the Italian coach taking over a side that stuttered to a seventh-place finish last term.
