That's the problem, Inter has a difficult game in the next round, it will be a game against Lazio who defeated Napoli twice in less than 7 days. If Inter wins they will be at the top of the table and Inter's next games are games against easy teams, so I assume that Inter will be able to win the next 6 games. Only after the next 6 games will Inter play against strong opponents like Juventus, Milan, Fiorentina and Napoli. That's why in my opinion if Inter can win the next 6 games and then win the games against Juventus, Milan, Fiorentina and Napoli, then Inter will be champion.
Inter Milan have opportunity reach to the first standings behind three points remaining awhile from Napoli and still have one postponed match against Fiorentina. For the next games Inter Milan have difficult opponent teams Lazio with impressive performance defeating Napoli last match back to back in domestic league and Copa Italia matches.
In domestic league, Inter Milan unbeaten last eight matches in a row but have bad performed in Champion League yesterday night after defeating by Bayern Munich.
I don't think last defeated in Champion League will be problem for Inter Milan at upcoming match against Lazio, its important match for securing top position standings and Lazio have the same opportunity behind both teams having the same points awhile. Now race for the first place very interested behind Atalanta having three points left but their position not comfortable yet if loss upcoming match.
