Red Star will not lose today, they may even beat the shaken Benfica. It is difficult to play in the stadium of the stars and more than one team has experienced it on their backs. Benfica as a guest play hard, it is evident from the statistics and the matches played against Famalikao and Morainese.
Visiting the Mala Maracana in Belgrade will not be easy for the much classier Portuguese club. However, I don't think there will be a surprise Smelo 2 for Benfica.
