For now, Lozano will walk out onto the fabled pitch as a visiting player. But after being informed by his agent that there was interest as a result of his strong performances in the World Cup for Mexico, which included a game-winning display against Germany, his dream is perhaps not so far away.
"It would be a dream to come to this club, but right now I am focused on PSV and enjoying my football," he added.
"It's a dream come true [to play at Camp Nou]. I never thought I would. Thanks to God I'm able to. It's an important game for me and I want to take advantage of it.
"I had a number of posters on my bedroom wall growing up, one of them was a Barcelona poster. They represent a lot across the world. It's the most important game of my career so far, a game against a great team, in a great stadium against really good players. I am going to enjoy it."
