Napoli under Mazzari has poor records for away matches in Serie A because recently Napoli has suffering 3 consecutive loses at this competitions and the latest is Napoli have to lost with big scores from small team Torino
There is rumor that Napoli has a meeting with Jose Mourinho to discuss about a coach position in their club. Napoli have better finance than Roma and Jose Mourinho can feel better there. So far, two coaches of Napoli in this season, Rudi Garcia and Walter Mazzari did not do their management well.
With latest news that Mourinho refused offers from Al Shabah because he wants to stay in Europe, it seems the coach position of Mazzari can be changed in this January. Napoli actually want to rejoin top four as soon as possible and really want to end this season in top four. They are starting to get familiar with Champions League and don't want to miss it next season.
if we see from these statistics i think Lazio have slightly good chance to win this match moreover they playing at their home ground besides that in Serie A Lazio have already win 7 times at their home so this proven although Lazio performance still not consistent i think Lazio was hard to beated at Olimpico stadium and i know this match is hard to predict but after seeing these records probably Lazio can being an the winner of this match
Generally Napoli and Lazio don't have big differences in Serie A with almost similar total points earned so far. Their recent forms are different and can help Lazio to win this match if Napoli can not end their bad streak. Lazio are not consistent with their performances so it's hard to say they will have too much chance to win this match. Just like 60 for Lazio and 40 for Napoli in their chances to be a winner.
