The gesture carried even greater meaning considering Bartra was born and raised in Catalonia, came through Barcelona's La Masia academy and was himself a casualty of a terrifying bomb attack on the Dortmund team bus on 11 April 2017.
A day before the game, the 26-year-old paid his respects via social media to those affected by Thursday's terror atrocity: "Where I was born, where I grew up and where I have the people I love. All my support to families. I love Barcelona."
