Manchester United could play Manchester City in the United States this summer in the first "derby" between the teams played outside England.

Jose Mourinho is understood to want to take his players to California to avoid the chaotic preseason preparations endured by his players in China earlier this year.

City and United were due to face each other in Beijing in July 2016, but torrential rain meant the pitch at the Bird's Nest Stadium was unplayable and the game was called off less than six hours before kickoff.
