Napoli didn't sign a big name player in January, and that's OK. This team is better in 2013 than it was in 2012, and there is no doubt about it.
In addition to key players showing remarkable maturity and progress, players like Edinson Cavani, Marek Hamsik and Lorenzo Insigne, the Partenopei also made some quality depth additions in January.
Striker Emanuele Calaiò was the next addition for Napoli from Siena. Like Armero, more of a depth move, but a necessary depth move since Eduardo Vargas is on loan. At 31 years old, he provides a steady veteran presence and could add some production as he had four goals and two assists in 18 appearances for Sienna.
Right at the deadline, Napoli made two solid additions in FC Porto's Rolando and Croatian youngster Josip Radosevic. Rolando gives Napoli another solid option for their back line. Radosevic gives them another young, budding talent with quality upside.
The key for Napoli has been the progress of their young core. With these new additions, it gives them more depth with players who have room to grow.
Yes, losing Ezequiel Lavezzi last Summer was tough. He's incredibly talented, but him leaving made it possible for younger players to show what they can do. Napoli wasn't the only team hurt by Paris Saint-Germain's influx of spending, but they've certainly handled their losses as well as any other club.
The club is just three points from the top of the table and seems to have nowhere to go but up as 2013 progresses.
