A meeting of five-time champions took place on Friday as the San Francisco 49ers hosted FC Barcelona at Levi's® Stadium.
The European soccer giants spent an hour practicing on the field ahead of the club's soldout match against Manchester United on Saturday.
"It's a spectacular stadium," Barcelona midfielder Sergi Roberto said. "They tell me it's new and it's amazing. It's the first time I've been inside an American football ground and it'll be a pleasure to be able to play here."
After Barcelona wrapped up its preparations, three of its star players stuck around to meet up with 49ers standouts Eric Reid and Joe Staley.
