Barcelona remain undefeated at the end of Group F qualifying in the 2019 UEFA Champions League, as they defeated Inter Milan 2-1 on Tuesday at the San Siro.
The loss sees the Italians crash out of the competition after Borussia Dortmund beat Slavia Prague 2-1, claiming the second qualification spot.
Carles Perez gave Barcelona a 23rd-minute lead after Inter's Romelu Lukaku had a goal ruled out for offside in the opening moments.
The San Siro was on its feet a minute before half-time when Lukaku smashed his deflected effort into the bottom corner, with Antonio Conte elated in the technical area.
