Having already won Group F and clinched a berth in the Champions League knockout stage, Barcelona didn’t even bring Lionel Messi to Italy.

Turns out they didn’t need him.

Ansu Fati became the youngest scorer in Champions League history in the 86th minute as Barca beat Inter Milan 2-1 and doomed the Serie A leaders to an early Champions League exit by virtue of Borussia Dortmund’s 2-1 win over Slavia Prague.

Elsewhere, Lyon rallied from a two-goal deficit to draw RB Leipzig 2-2 and clinch advancement.

Inter Milan wasteful as Barcelona wins

Inter put the ball in the back of the net several times on Tuesday, but only one goal counted.

That came via resilient striker Romelu Lukaku, who scored right before halftime to level the match and give the hosts hope (via Turner Sports):

But Lautaro Martínez was ruled offside on two late chances he looked to have converted, and Fati made Inter pay:

Fati is only 17 years old, and 155 days younger than Olympiacos’ Peter Ofori-Quaye was when he set the record in 1997 for youngest Champions League scorer.

For as great as Inter has been thus far in Serie A, this loss will string. Beating Barcelona is no easy feat, but the Catalans have been Messi-or-bust for quite awhile now. And even without facing Messi, it’s Inter who busted, bereft of the cutting edge called for by the moment.

Borussia Dortmund capitalizes on Inter’s loss

Dortmund entered the day tied with Inter in Group F on seven points, and looked to have the easier fixture on paper.

That’s how it played out on the pitch too, with Marco Reus setting up Jadon Sancho to give Dortmund an early lead in the 10th minute. Tomáš Souček drew Slavia Prague level before halftime, which made for some nervy moments.

Then Julian Brandt blasted home a wide-angle goal that punched Dortmund’s ticket to the knockout stage:

Lyon overturns deficit to move on

Two first-half penalties plunged Lyon into a hole. Houssem Aouar and Memphis Depay clawed them out of it.

Aouar curled home a lifeline shortly after halftime:

And Depay struck late to seal advancement:

Emil Forsberg and Timo Werner scored the penalties for RB Leipzig, which finished atop Group G.

Lyon and Zenit Saint Petersburg entered the final group matchday tied on seven points apiece, with Zenit having the superior goal difference. But the Russian side was dominated 3-0 by Benfica, opening the door for Lyon to advance with a result.

Thanks to Aouar and Depay, Lyon ran right through it.
