PortoRed Star

Porto has had an impeccable start to the season: they have won all eight of their competitive matches, scored a total of 20 goals, and conceded only one. Diogo Costa has kept seven clean sheets, and the defense's xGA metric is exceptionally low. At home, their goal average is over 3, with several players showing good form in attack (Omorodion 5, Sainz 2 goals).

Crvena zvezda might be achieving goal-laden victories in their domestic league, but their away record in European competitions is weak (12 defeats in their last 16 group stage matches). They played the 1-1 against Celtic at home, and their defense's average of 0.86 goals conceded/90 in the Serbian league has not yet faced opponents of Porto's caliber.

• Porto goals: over 2.5/game, home xG > 2.0.
• Red Star away in Europe: averages 1.6 goals conceded, no goals scored in the last two high-stakes matches.
