The 2011 Emirates Cup was a pre-season football friendly tournament hosted by Arsenal at its home ground, the Emirates Stadium in London. It was the fifth Emirates Cup, an invitational competition inaugurated in 2007. Held on the weekend of 30–31 July 2011, the participants were Arsenal, Boca Juniors, Paris Saint-Germain, and New York Red Bulls. The inclusion of the Red Bulls meant Thierry Henry returned to play against his former club, Arsenal. The 2011 edition, with the Red Bulls and Boca Juniors, also marked the first time clubs outside of UEFA's jurisdiction had participated in the competition.
