The match of week 30 is not likely to be a difficult game for Intermilan, like as you said Intermilan and Empoli have a much different quality team and I think it will be very easy for Intermilan to overcome the resistance from Empoli, ..
Surely.
This match won't be bother for Inter Milan.
Empoli is not that strong enough to beat Inter Milan at the moment. unless there is a miracle. But, this won't be easy to get any miracle.
What will be quite a tough match for Inter in Serie A is around:
AC Milan and Probably Lazio. In fact, they won't necessarily give Inter a very strong match, if you look at their performance so far. Not underestimating, but if calculated based on recent statistics and facts, it seems that Inter Milan will benefit from all this.
