Geoffrey Kondogbia has a fever and is a major doubt for Sunday night’s encounter with Roma in San Siro.
The French midfielder had aimed to return to the side after serving a suspension, but ran a high temperature yesterday as he suffered from flu-like symptoms.
Stefano Pioli and his staff are determined to help him recover in time as Marcelo Brozović is not 100% fit either, although the Croatian could yet make the bench this weekend.

In what era does it take 5 days to recover from flu like symptoms ? Gaglia, Kondo, Mario, Perisic and Candreva. Plus our master poacher Icardi is back and Eder, Brozo and Gabigol as super sub will have any side in Serie a scared. Firmly believe 3 points is on the cards here for Inter.
You forgot Banega another super sub
In our era? Flu-like symptoms presents itself in a vast variety of illnesses ranging from fairly harmless conditions like the common cold to fatal diseases like rabies. So its pretty impossible to know just by “Flu-like symptoms”.
Since he has a high fever, its probably a case of the flu. Having high fever for a few days makes you very fatiqued an extended period of time afterwards.
So its probably very likely he will miss out or be on the bench.
I think you underestimate Roma. they are doing very well currently. so I don’t think it’s on the card. it will be a hard-fought battle.
