Nineteen-year-old Marcus McGuane, who left Arsenal in January, came off the bench at the Camp d'Esports Stadium in an unofficial fixture that Barca won 4-2 on penalties, after a goalless draw in normal time.
Since then the midfielder has made four appearances for the reserve side and now one for the full senior side, even if it was a Barca first team heavily embellished with second-string and "B" team players for a match nobody outside Catalonia really cares about.
Gary Lineker was the last English player to represent Barca, the former England striker joining the Spanish club from Everton in 1986 and winning the King's Cup and European Cup Winners Cup before moving to Tottenham Hotspur in 1989.
Lionel Messi's first-half free-kick was the only goal in Barcelona's decisive 1-0 win over Atletico Madrid on Sunday - putting them eight points clear at the top of La Liga with 11 games left of the season.
McGuane had spent more than a decade in the Gunners' youth academy system but chose to pursue a career overseas in order to boost his chances of tasting first-team action. A certain number of B players must be included in the squad for the competition and only two teams - Barcelona and Espanyol - are involved.More news: Delpha Capital Management LLC Takes Position in Alexion Pharmaceuticals, Inc.
