Chelsea announced an extra friendly game to their end-of-season tour of America as they will play Manchester City at Yankee Stadium in New York.
The clubs are already set to face each other in St Louis, at the Busch Stadium on May 23, but have now announced the additional fixture two days later.
The games are part of both clubs' plans to increase popularity in the USA, and for Chelsea it marks a return to the venue they played at last year, the home of the New York Yankees.
"The club is excited to be playing a double-header in the US this May and thrilled to be returning to Yankee Stadium," Chelsea chief executive Ron Gourlay told the club's official website.
"We were delighted to take part in the first-ever football game there, and we received sensational support in what was a sea of blue fans inside and outside the stadium that day.
"Spending the week in St Louis and New York also provides a great opportunity for the club to reconnect with our US fans before we head to Asia in July for pre-season.
"America has long been an important place for Chelsea Football Club, and we have seen first-hand the continued rise of the game's popularity."
Current Premier League champions Manchester City are also looking forward to the game as they aim to build on their popularity in America.
"Since City's visit to the United States in 2010, our relationship with North American fans has continued to grow," City spokesman Ferran Soriano said.
"We are enthusiastic believers in the development of soccer in the US and have seen first-hand the passion that North American supporters have for the beautiful game. We are delighted to bring City to their doorstep."
The game has also proven popular with American fans, as all tickets for the first friendly in St Louis at the 46,861-capacity Busch Stadium sold out within 20 minutes of going on sale.
