Yesterday, the Internet briefly went crazy when rumors began to circulate that Ronaldo had once again left training and might possibly be out of the World Cup altogether.
However, those rumors appeared not to be true as Portuguese goalkeeper Beto later stated that Ronaldo was actually "100 percent fit," as reported on FoxSports.com.
Assuming he does play, the U.S. will certainly have to think about how they want to set up against the Real Madrid star. He will likely play on the left side of Portugal's attack, meaning that Fabian Johnson, the United States' right-back, will draw the duty of marking Ronaldo through much of the game.
Providing cover at right center back will be Geoff Cameron, and luckily for the U.S., Cameron and Johnson are their two most experienced defenders, playing in the English Premier League and Bundesliga, respectively.
Helping Johnson at right midfield will probably be either Alejandro Bedoya or Graham Zusi, but another interesting option would be to move Jermaine Jones to the right side and switch Bedoya or Zusi over to the left.
Playing Jones on the outside certainly isn't his natural position, but as he proved against Ghana and previously against Nigeria, he can be counted on to provide defensive support in a wide role when needed and certainly won't shy away from putting in a hard tackle or two on the Portuguese attacker.
