International soccer superstar Mesut Ozil is conquering the U.S. ... at least in the Hollywood club scene ... where he's been MOBBED by fans and paparazzi all week long.
The 26-year-old Arsenal star -- who won the World Cup with Germany last year -- got the rock star treatment at Bootsy Bellow's nightclub on the Sunset Strip.
We asked what he thought of the U.S. Women's soccer team -- and it sounded like he told us, "They look real good."
While Ozil left the club solo last night, he had more than his share of ladies on Sunday night ... when he left Henry's with TWO hot blondes.
Soccer -- who says Americans don't care?!
