I also find the match between PSV and Benfica very interesting. Those are two teams that are evenly matched. There are also teams in the last round that make you wonder if they are worthy to play in the main tournament. But the cash register does ring well.
That match will be really intresting to watch. Two hardcore teams and top of their league every year playing. But as far as i watched and analysed PSV i think they will be in advantage in this duel. If Zahavi plays like he does i think they have a lock win. They already destroyed Galatasaray
