Ever since Erick Thohir has taken over as President, Inter has been in a free fall in the Serie A table.
The Nerazzurri have only won one of their last five games domestically after a good start by new coach Walter Mazzarri.
Even though it is widely expected that the Indonesian billionaire will invest in the club, the latest rumors suggest that Fredy Guarin could be on his way out of the club.
Guarin is by far Inter's most dynamic and skilled midfielder, who is a threatening box-to-box presence who always has his eye on goal and creates with an abundance of technique.
President Thohir has said it himself that Guarin could be on the market this January, and it's a head-scratching decision from an owner that bizarrely stated that his two favorite Interisti were seldom used Nicola Ventola and Obafemi Martins.
Inter's defense is the biggest problem at the moment, with a few players looking way out of their element in Mazzarri's 3-5-2 formation.
While the full-backs Jonathan and Yuto Nagatomo have done well in their new wing-back positions, the likes of Andrea Ranocchia and Juan Jesus have hit rough patches, with Hugo Campagnaro being the only one that understands Mazzarri's defensive scheme perfectly, as they were together at Napoli as well.
The most important position Inter needs to fill at the moment is in the center of the park and on the back line.
A box-to-box defensive midfielder like Daniele De Rossi would be ideal, as Esteban Cambiasso is hitting the twilight of his career. However, there are more realistic targets in the market.
If Guarin went to Chelsea, it should be on Thohir's list to acquire someone like the Brazilian Ramires.
If Inter doesn't substitute the Colombian assuming he does leave, they'd be stuck with the likes of Saphir Taider as constant starters. Taider has largely underwhelmed and isn't ready to be part of the main rotation yet if the team is truly serious about contending in Europe again.
Where does Inter need to strengthen?
The defense is also in desperate need of reinforcements. Someone like Miranda of Atletico Madrid would be perfect. Miranda has really exploded on the scene this season with Atleti and is one of the main reasons for their rise to the top of the La Liga table.
With a back three of Miranda, Juan Jesus and Hugo Campagnaro, Inter could boast one of the most technical and mobile defensive lines in Italy, and it would be very hard to catch them off-guard on the counter-attack.
Inter are tied with Hellas Verona for fifth place in the Serie A table, and have been in a landslide since Thohir took over for Massimo Moratti.
While the club has some real interesting young prospects like Mateo Kovacic, they need to strengthen plenty if they want to be taken seriously as a Scudetto contender and get themselves back into the Champions League.
