Italian newspaper Corriere della Sera claims the Lazio ace has emerged as a January transfer target for Liverpool boss Brendan Rodgers.
The 28-year-old is a regular for Italy and featured at the Confederations Cup last year as his country made the semi-finals.
He is expected to play at the World Cup this summer, and the report claims a bid in the region of £9m could be enough to take him from Rome to Liverpool.
The Reds are expected to be busy in the January window, with Rodgers keen to carry the club's momentum into the New Year.
They currently sit fourth in the Premier League table, six points off Arsenal in top spot.
But realistically, Rodgers' remit this year is to consolidate a top four place and secure a vital place in next year's Champions League.
