Juventus GM Beppe Marotta believes Napoli are enjoying an impressive campaign thanks to a quiet summer market.
Marotta argues not having to make major changes to their squad has been an advantage for the Azzurri.
He said, "It's no coincidence that Napoli are top of the league right now, and if you look at Napoli's summer transfer campaign they only did a couple of deals because they confirmed most pf their players, who are great.
“It's the same for Juventus, the same for Real Madrid and the same for Manchester City; the best teams don't have to use the transfer market to revolutionise their teams.
“We've made transfers to prepare for our future, we've brought in young people like [Rodrigo] Bentancur, Bernardeschi and Douglas Costa, young guys who will have time to show their ability.
“We have a big squad with great quality, considering that last season we played 57 matches and that's without considering the national teams.
“So it's logical to set up a numerically strong squad.
“Will we return to the transfer market? No, absolutely not."
