Gazzetta dello Sport write about the training session ahead of the game against Atalanta in which Nainggolan seemed to not be at his best, it appears that he will be replaced by either Joao Mario or Borja Valero for that game.

“Radja Nainggolan has ended the training session with some individual work. It is nothing to worry about but it is a sign that the Belgian will likely not feature the full 90 minutes in Bergamo. After the last two brilliant games and renewed confidence with the fans, it will be difficult to ask Joao Mario to sit on the bench for this game. The Portuguese was an important aspect of the 4-3-3 that was deployed against Lazio and Genoa. This new formation also helped Gagliardini shine as he managed to score a brace against Genoa. It is likely that Spalletti will confirm the trio of Brozovic, Gagliardini, and Joao Mario in midfield against Atalanta. Icardi will also return to the starting line up with Perisic and Candreva on the wings.”

Here is the Gazzetta dello Sport’s predicted line up for Inter ahead of the game in Bergamo:
INTER (4-2-3-1): Handanovic; D’Ambrosio, De Vrij, Skriniar, Asamoah; Gagliardini, Brozovic, Joao Mario; Candreva, Icardi, Perisic.
