Chelsea knew they were up against it in the Nou Camp, and would need all of their grit and skill to climb the mountain.
They ended up making that mountain significantly taller within two minutes, and Messi burst into the right side of the box to score.
Ousmane Dembele added a second after Messi tore through the Chelsea defence and put the tie to bed with a powerful drive.
