The January transfer window hasn't been quite as star-studded and productive as Napoli fans may have been hoping for, but it hasn't been dull. Moves in, moves out, rumors galore, and a few frustrations along the way just for kicks. Now it's coming to a close, with less than 24 hours to go. What's in store on this last day of transfer action?

The transfer window closes at 11 p.m. CET (5 p.m. ET) tonight, not giving Napoli much time to finish their work. They've completed two transfers already this month, with a third expected to be finalized today. There's still plenty of rumors surrounding other interests and bids that Napoli have in play, so this could be a very, very busy day for the partenopei.

Let's run down what's already been finalized before moving on to the rest of what might happen.

• Napoli signed Alberto Grassi from Atalanta in a deal worth €8 million up front with another €2 million in potential bonuses. He suffered a knee injury in his first training session and is expected to miss three weeks.
• Napoli signed Eddy Gnahore from Lega Pro side Carrarese for an unknown transfer fee, and was immediately loaned to Carpi for the remainder of the season.
• Jonathan De Guzman was loaned to Carpi for the remainder of the season.
• Camilo Zuniga was loaned to Bologna for the remainder of the season.
• Henrique was sold to Fluminese for a €2 million transfer fee.

And now let's look at what should be finalized today based on what we already know:

• Vasco Regini should officially join from Sampdoria on a loan with an option to buy in the summer.
• Josip Radosevic looks set to join La Liga side Eibar on loan with an option to buy in the summer.
• Nathaniel Chalobah could also become a full-time Napoli player, as they're believed to be working on securing a permanent transfer of the Chelsea loanee.

So what else can we expect Napoli to do today? They're rumored to be close to deals for several high-upside youth prospects -- something we've been begging them to do for years -- as well as additional links to midfielders and defenders, the two position groups Napoli have seemed to prioritize this month. No word on strikers or wingers, though.

There's also been talk of a few potential departures, but every rumor and report on that train of thought has ended with "but Napoli turned them down flat." We might see a couple of loan departures to get certain younger players some playing time, but nothing significant.

Stay tuned. It looks like today is going to be a busy day.
