PSG and Barcelona meet Tuesday in a matchup between two undefeated sides. PSG has won their first two League Phase matches against Slovan Bratislava and Manchester City, extending their Champions League dominance. Barcelona arrives similarly hot, with victories over Feyenoord and Galatasaray plus a perfect 9-0 record in La Liga featuring 39 goals. PSG will be without defenders Eric García and Jules Koundé, while Barcelona have Raphinha available for the contest and Sunday's El Clásico.

Liverpool seek a third consecutive win at home against Villarreal but face absences from Dominik Szoboszlai and Jeremie Frimpong due to weekend injuries. Manchester City host AEK Athens with Erling Haaland expected to return after limping off Saturday. Bournemouth's Antoine Semenyo suffered a knee injury that will sideline him for at least eight weeks.

Tuesday's 3 p.m. ET fixtures include Roma versus Slovan Bratislava, Porto hosting PSV, Napoli against Bodø/Glimt, and Stuttgart facing Atlético Madrid. Fenerbahçe led Slavia Prague 2-1 and Sabah drew 1-1 with Borussia Dortmund in earlier action.
