Inter Milan defender Jonathan has no doubts new coach Walter Mazzari is bringing out the best in him.
Jonathan has been outstanding in the opening rounds of the new season.
"The merit of my recent performances have been because of Mazzarri," he told Sport Mediaset.
"The Coach has given me confidence and that is really important.
"Now we have to play Juventus, which will be tough. They are a strong team. Conte has worked well for years and manages to get the best out of his players.
"Playing at San Siro will give us an extra boost though.
"I'm sure we will give them a great challenge and maybe even beat them."
