Arsenal are reportedly in talks over a five-game USA tour for the summer of 2019 that would see them play in New York and Chicago.

Arsenal are already expected to play in Uganda although this has not been confirmed by the club.
According to the Uganda National Council of Sports Chairman, Bosco Onyik, told Xinhua, “We went to London last month on January 16th and had three meetings with management of Arsenal FC with the aim of partnering with them.
“We agreed that they will train some of our coaches, give the Uganda Cranes [the] chance to train at the Emirates Stadium in London, build an academy and also have their team to visit in June next year to tour Uganda and play some matches.”

Arsenal’s trip to the USA will no doubt form part of 2019’s International Champions Cup.
No games have been confirmed for the 2019 iteration of this competition but rumour has it that Man United are heading out east which obviously opens a space for Arsenal in the States.
Arsenal played their first Stateside game since 1989 when they travelled to face the New York Red Bulls in 2014.
It has not been explained why they have opted for New York and Chicago, or if they will travel to any other cities, although I know a few people who live there who are going to be wetting themselves with excitement!
