The International Champions Cup comes to AT&T Park tonight for a matchup between Juventus and Everton, and both clubs will be fielding rosters loaded with stars.
Some of the high-profile stars who will compete in today's showdown include Marouane Fellaini (Everton), Tim Howard (Everton) and Carlos Tevez (Juventus).
It will be the most difficult test for both teams this season.
"It's going to be a terrific test — this is as good as it gets in terms of games for us," Everton manager Roberto Martinez said on his team's website.
Everton has had three preseason games this month, losing to Austria Vienna 2-1 before beating Accrington Stanley 4-1 and Blackburn Rovers 3-1.
Juventus also has had three games, beating up on Aygreville 7-0 and then playing AC Milan and Sassuolo to 0-0 draws.
The winner of tonight's game will face the winner of Real Madrid and the Los Angeles Galaxy, who face off Thursday in Phoenix.
