I think Livorno is closer to the victory on Stadio Alberto Braglia in Modena. Both teams are incomplete for this match, but I think Sassuolo handicap is bigger. Sassuolo will be without important defender Lino Marzoratti (played 13 matches) who is suspended, while three more players are injured - the key midfielder Gianluca Sansone (played 17 matches and also scored 6 goals which makes him best scorer together with Boakye), another key defender Alessandro Longhi (played 17 matches) and important midfielder Carl Valeri (played 10 matches). It is clear the coach Fulvio Pea will have lot of problems for this match. Even more as Sassuolo home for isn't too impressive in the last period. They have two draws and one defeat in last three rounds, scoring just one goal (Marchi has scored that lucky goal in the last minute of the game against Brescia) on the mentioned games:

26.11. Sassuolo - Padova 0:1
19.11. Sassuolo - Brescia 1:1
05.11. Sassuolo - Torino 0:0

It is true that Livorno coach Walter Novellino also has some missing players (Knezevic and Schiattarella are suspended), but I believe he will find adequate replacements. Novellino is an excellent coach, he has Serie A experience leading Sampdoria in the past. He will base his tactic on strong defense and fast counterattacks. I don't think Sassuolo will score here. And I think Livorno will win, just as two seasons earlier, on 16.05.2009.
