Thohir is already working towards making future additions to the squad in the winter transfer market.
"We shall see what is needed," he said. "Perhaps we are in need of a quality midfielder at the same level of (Inter’s) Hernanes or (Mateo) Kovacic and also a skilful striker who has good aerial ability.
"I can’t say anything further because we still need to evaluate everything.
"The defence is fine and the midfield is doing well too – we have important players who are performing to a high standard, such as Kovacic, (Gary) Medel and Hernanes."
Inter, who are also competing in the Europa League this season, next face Napoli at the San Siro on October 19.
