Atalanta striker Christian Vieri is to undergo a second operation on his injured knee.
Vieri picked up a knee injury towards the end of last season, but an operation in May failed to cure the problem.
“Christian will have to undergo a little surgery to his knee,” Atalanta coach Stefano Colantuono revealed.
“As for the time of recovery it doesn’t change a lot. 20 days, more or less, won’t make much difference.
“We hope to have him fit for the end of January or the beginning of February.”
