Lazio coach Maurizio Sarri admits he'd like to see the squad improved this month.
However, Sarri knows the budget is limited at the Romans and he won't complain.
After the Coppa Italia win against Udinese he said: “If it were up to me I would make the club spend a billion, but the needs of the clubs have to be taken into account.
"Lazio has a very careful management, they will never make many purchases in one transfer session. I knew this before.
"The important thing is that the club is mentally willing to accompany us in our growth.
"The team is growing, especially in spirit. It seems to me that she is more willing to sacrifice and fight."
