Finally the transfer window has been closed for most European leagues including the Serie A.
Let's have a look at top spenders.

Source: TransfermarktMilan has invested a lot in transfers after bringing Allegri right? Still not even close to a PL team, I know.

But Serie A teams usually don't spend huge money on single player.
Anyways Milan got a really good income from departures at the same time. But will these transfers be enough for them to be competitive you think?
in practice the one that spent the most without any returns is Como with a 93 million deficit
that's a really big amount of money
I don't know how they planned to cover the costs, but it's impressive and scary the expense they made.
I honestly wouldn't be able to manage a team, I'd be anxious
