I think the hosts will win, although not easy.
Bayern Munich vs Benfica
Barcelona vs Atletico Madrid
I think Bayern Munich can easily win versus Benfica. I pick Bayern Munich -1.75 goals and over 3 goals. I'm sure it would be an easy win for Bayern Munich.
I would bet against your pick , if you think bayern munich would win easily then I think it wouldn't easy one.
Last time bayern munich only won 1-0 at home , and this time I think they would win 1 goal margin only like 1-0 or 2-1 , so I would pick benfica +1.5 @2.1 .
I think that Benfica are underestimated in this match. Benfica won last eight matches in a row and I support them to surprise Bayern today. Hosts did not managed to win half from last 8 matches in all competitions in regular time.
