"In January it is difficult to take good players," he said. "There is no one club that can sell good players in January.
"Maybe we can find young players. If we have this chance in the next 10-12 days, probably we can do something but I am not sure."
The Italian confirmed that Sweden striker John Guidetti, who has not made a senior appearance since March because of a virus, will not be loaned out.
"Guidetti is not ready to play in this minute," he added. "It is difficult for him to recover after his injury. I think he needs another two months."
