Were Inter not among the top places (I think 2nd or 3rd) until around January? There was a 7-game winning run, with victories away to Lazio and Fiorentina and against Meelan that took us up the table.In Spalletti's first season we started well and were even top in December then dropped to 4th but in his second season I don't remember a strong start or being on top at any stage, tbh.
I'm certain the same will happen to Napoli. I'm not saying that out of spite - I like them. And I think they have more depth than Inter had in Spaletti's 2nd year.
But the defensive depth is thread-bare.
