One of them were Carles Perez, who bagged the opener on 23 minutes for the Catalan side.

Despite an equalizer from Romelu Lukaku right before half time, substitute Ansu Fati, also took his chance to shine in the absence of the world's best player, playing a beautiful 1-2 on the edge of the area before smashing home on 86 minutes and Barca held on for the win.

Inter exited at the group stage of the tournament for the second season running, they have Europa League football to look forward to.

In the game's other match, Borussia Dortmund beat Slavia Prague 2-1 in Germany, who went through in second place behind last season's semi-finalists.
