The future of Inter owned midfielder Radja Nainggolan is unclear as there are two things that make a permanent stay in Cagliari unlikely, according to a report from today’s paper edition of the Rome based newspaper Corriere dello Sport.

The report details how the 31-year-old Belgian midfielder feels at home in Sardinia and is enjoying his time there, but still may not be able to stay there beyond this season. The first problem is that he currently earns around €4 million a year, a salary too high for the Sardinian club. The other problem is that he is worth around €15-20 million, expensive for the Rossoblu considering the current financial climate.

Cagliari president Tommaso Giulini discussed the importance of building a strong squad in the last few days, saying: “We will see the players on loan who are doing well and who will deserve a chance for next year. We intend to build a team that can make a good impression and we hope that, if we can play these thirteen games that we are missing, we will get indications on how to continue with this squad.”

Nainggolan has made 24 appearances across all competitions so far this season for the Rossoblu, for a total of 1943 minutes. In that time, he has scored five goals and provided six assists, regaining the form that he was known during his time at Roma.
