English Premiership champions Chelsea beat UEFA Champions League runners-up AC Milan 1-0 in their first US tour match on Sunday.
In the 12th minute, Robben took a pass from Claude Makelele and blasted a 20-meter shot into the bottom right corner.
AC Milan, losers on penalty kicks to Liverpool in this year's UEFA Champions League final in May, were without Ukrainian striker Andriy Shevchenko as well as Brazilian star Kaka and their captain Paolo Maldini.
Argentina's Hernan Crespo was listed in the starting lineup for Chelsea against AC Milan, the club for which he played last season.
AC Milan and Chelsea will meet again next Sunday at Giants Stadium in East Rutherford, New Jersey, to conclude their US tour.
