The other semi-final match between Inter and Lazio is certainly highly anticipated and it is curious who will qualify for the final against Napoli. Maybe if it was clear from me I would wait for Inter because they have a better attack and Lazio is only strong in defense but not good in attack. But the thing that is quite worrying is that the match will end in a draw in normal time and there I might be blind and not know who will go through extra time.
The match is already underway and Inter Milan is leading with a score of Inter Milan 1 - 0 Lazio, Marcus Thuram has an important role here because the 1 goal Inter Milan has is the goal he scored.
Just like you, I also have no doubts that Inter Milan will win this match and will meet Napoli in the Final, but, as long as the match is still going on, we actually don't know what will happen next. Remember that Napoli were able to score 2 quick goals in the final minutes of their match against Fiorentina yesterday.
