Inter Milan GM Beppe Marotta says the team's current success began with Luciano Spalletti.
Simone Inzaghi's Inter are now well placed to win Serie A this season.
Marotta told DAZN: "The new cycle began with Spalletti, then was developed with (Antonio) Conte, with a group that remained unchanged in terms of its winning mentality and play.
"Then Inzaghi arrived who, with his light-heartedness, created a fun atmosphere, with a great relationship with the players. There are merits from Conte, others from Spalletti and today from Inzaghi. In the locker room there is a very positive air, not only due to the results, which are important.
"We all have good guys, but we haven't won anything yet. We have 13 points more than last year, a +41 goal difference, but we haven't won anything and we will find the biggest dangers in the provincial fields, starting for example with Salernitana, which we will face after Roma.
"We are first but there is a lot missing."
