FC Porto lost to Bayer Leverkusen in the 1st leg, but that was on away field.
Now FC Porto are on home field and have advantages.
The AH line is in favor of FC Porto.
On the other hand, Bayer Leverkusen won 4 games in a row, but it is hard for them to win this game as the AH line is with long odds.
So the hosts should be supported to win in this game.
