Tomorrow's game between Inter and Napoli will be very important for the race for the title.
Inter is playing away, but they are doing better than Napoli. During the last games, Napoli latest victory was five games before while Inter Milan won two out of the three last games. Napoli was defeated by Como, a relatively weak team while Inter lost in front of Juventus and Fiorentina which are good teams.
As you mentioned a draw might be the best option but only for Napoli because Inter Milan want to run alone for the title for sure.
If we consider the latest performance of these teams, I agree that Inter Milan looks like to have a bigger chance to win the match. Napoli performance in the last 4 matches looked very bad, they never win a single match. They got 3 draws and they lost 1 match. It is a bit different with Inter Milan, they still could win 2 matches although they got 2 matches. However, Napoli must have a little advantage because they will play at home. Napoli must be difficult to beat at home. So, it is possible for the draw result although I assume Inter Milan will get the full points.
