Benfica host Fenerbahçe...
First of all Benfica haven't conceded any goal in 6 official games so far. Scary right?

This is what makes things really hard for Mourinho. He'll probably prefer a cautious game unless his team concede. He has more chance by penalties.
Bookmakers don't rate this game too badly for Fenerbahce:
1.73 - 4.0 - 4.60
Benfica are big favourites, but even a win in regulation time is estimated at a solid 20% for Fenerbahce. The Mourinho factor could work. I don't know what scenario the game will follow, but the most rational thing that comes to mind when I think about a possible Fenerbahce victory is a 0-0 score and a successful penalty shootout.
