Roma and Liverpool had reached an agreement over a transfer for the 31-year-old earlier this month, but the goalkeeper turned down a move as he was not prepared to take a pay cut to move to Anfield.
“I have only received an official offer from Liverpool,” he told Italian newspaper Il Tempo.
“But I could not accept those conditions. I would have had my salary cut by 60 per cent.
“After signing a five-year contract extension with Roma in 2008 and having given a knee for Roma’s cause, I am unwilling to give away money.”
