Six years ago, Barcelona and Manchester United set an area attendance record for soccer by drawing 81,807 to the Landover venue. The Spanish powers also visited FedEx in 2015 by facing Chelsea in front of 78,914. A year earlier, Manchester United attracted 61,238 for a friendly against Inter Milan.

The issue always overshadowing these matches is whether the superstars will play significant minutes — or play at all — in largely inconsequential events. Typically, though, they do travel and play portions of matches. Some players, though, are excused if they’ve had a busy summer with their respective national teams.

Barcelona’s Lionel Messi (Argentina), Luis Suarez (Uruguay) and Neymar (Brazil) are not involved in this summer’s most significant international competition, the FIFA Confederations Cup in Russia. Messi, the five-time world player of the year, has yet to play in Washington, despite three opportunities: Twice with Barcelona, he was on break after national team commitments, and two years ago, he accompanied his national team but missed the friendly against El Salvador with a foot ailment.

There is a conflict of sorts this year: Three days later, Barcelona will face Real Madrid in Miami — only the second overseas renewal of the world’s most revered sports rivalry. Hence, Barcelona seems likely to save its top figures for the Clasico showdown. The Catalan side will also play Juventus on July 22 at MetLife Stadium in New Jersey.

In this La Liga season, Barcelona is in a neck-and-neck race with Real with 10 matches left. Barca is also preparing for Juventus in the Champions League quarterfinals after a historic four-goal comeback against Paris Saint-Germain in the second leg of the round of 16 this month.

Manchester United is the Premier League’s most decorated club but hasn’t won the first-flight trophy since 2013. The Reds are 17 points behind Chelsea and in fifth place, the same position they finished last year. They’ll face Belgium’s Anderlecht in the second-tier Europa League quarterfinals.

The squad features one of the world’s top strikers, Sweden’s Zlatan Ibrahimovic, and the world’s most expensive player, French midfielder Paul Pogba, whom United purchased from Juventus last summer in a $110 million transfer.
