Manchester United, Liverpool and Manchester City have reportedly agreed to feature in a pre-season tournament in the United States that will take place in 12 different cities.

The 2014 International Champions Cup will also include Real Madrid, AC Milan and Inter Milan and will culminate with the semi-finals and the final at the Sun Life Stadium in Miami.

Initially revealed by World Soccer Talk, the eight-team event is due to be announced officially on Tuesday, with Roma and Olympiacos said to be the other two teams who will compete.

The provisional schedule initially pits United against Roma in Denver, while Liverpool will face Olympiakos in Chicago, both on July 26, before City play Milan in Pittsburgh the next day.

The tournament, which featured Chelsea and Everton last year, will also include matches in Dallas, Phoenix, Charlotte, Ann Arbor and Hartford.
