ANN ARBOR -- Real Madrid ramped up the star power for its upcoming International Champions Cup match against Manchester United at Michigan Stadium on Aug. 2.

The team announced Wednesday that Cristiano Ronaldo is joining its roster along with goal keeper Iker Casillas, defender Sergio Ramos and midfielder Luka Modric.

All four athletes played in the 2014 World Cup.

Ronaldo, who is FIFA's reigning Ballon D'or Award winner (best male player over the previous year), suffered a knee injury in the tournament playing for Portugal.

His status for the game was in doubt when Real Madrid announced a 20-man roster for the ICC last week without its leading scorer on it.

In five seasons with Real Madrid, the forward has scored 252 goals in 246 appearances. He hasn't scored less than 50 goals in a season since 2009-10.

Casillas, Ramos and Modric joined the team in Los Angeles on Wednesday while Ronaldo will meet up with his teammates in California on July 26, the same day its scheduled to play Inter Milan in its opening match of the 2014 ICC tournament.

Real Madrid's second ICC match is against AS Roma on July 29 in Dallas, Texas before it travels to Ann Arbor.

Manchester United adds Javier Hernandez

Manchester United also made a roster move this week when it announced that striker Javier "Chicharito" Hernandez would play on the team's ICC tour.

The 26 year old played for Mexico in the 2014 World Cup.

Hernandez, who is entering his fifth season with Manchester United, made it to the United States in time to watch his squad beat the LA Galaxy 7-0 in a friendly exhibition on Wednesday.
