If both of them do not play aggressively then there is a possibility that there will not be many goals scored, because both of them play safely if both of them play aggressively then one of them will be kicked out of the current standings, both have the same points so whoever wins the match then he will shift Inter Milan or Lazio, but Lazio has the advantage in this match playing at home will be much more profitable than playing as a guest, Lazio must also be careful with Inter Milan's attacks because they could endanger Lazio's defense line.
Personally I don't think the Lazio vs Inter Milan game will produce a lot of goals and that's not because I'm unaware of how prolific both teams are but because I think both teams will be very careful in the back so they don't let in goals. I think the game is most likely to end in draw and if one team will steal all three points from the game, it'll be a narrow win.
