I don't think Inter will be daunted by what Napoli have achieved in their last 15 matches in Serie A, and they need to keep up the good motivation to get one step closer to the top of the table. Inter mustn't drop any more points if they want to fight for the title this season, so far the two teams are 11 points adrift which is actually very big, but Inter has the chance to reduce that gap to 8 points if they win.
Also Inter will have to work on this win to get into the top 4 and take advantage of the opportunities that arise. Lazio, who have the same points as Inter, seems to have won 3 points more easily because Lecce is not a strong opponent. There is pressure on Inter in this game, but they have to try their best.
I don’t know how the game will end, but I think that at least it will be productive - Napoli have the best attack in Serie A, and Inter have the worst defense among the first nine teams. And in general, Inter is extremely unstable - ten wins and five losses with zero draws. I don't understand how the bookmakers consider it a favorite.
Inter Milan might be in the second position, but to me, Juventus still has upper hand to beat Napoli than them.
