Hulking U.S. centerback Oguchi Onyewu is the first American player to take advantage of the team's impressive run to the Confederations Cup final, having signed a three-year contract to join Italian powerhouse AC Milan. It's a great move for Onyewu, 27, who becomes only the second U.S. international ever (after Alexi Lalas) to play in Serie A.

But the big question for Onyewu (and any other Team USA player) is this: How much will he play? It will be vitally important for U.S. players to be on the field for their club teams during a World Cup year. Onyewu's competition for playing time will be fierce, considering Milan's centerbacks include Brazilian Thiago Silva, Italian veteran Alessandro Nesta and Georgian Kakha Kaladze.

Then again, Milan has plenty of games this season now that it's back in the Champions League. What's more, Nesta (who's 33) and Kaladze (31) are older and prone to injuries.

All I know is it will be fun to see Onyewu with the Rossoneri when AC Milan tours the U.S. this month with friendlies against the L.A. Galaxy (July 19), Club América (July 22 in Atlanta), Chelsea (July 24 in Baltimore) and Inter Milan (July 26 in Foxboro, Mass.).

What do you think of Onyewu's move to Milan? How much playing time will he get? And which other U.S. players do you think will move to new teams after the Confederations Cup success?
