Zlatan Ibrahimovic -- Pool Pimpin' in Vegas (PHOTO)

He may hate our soccer team, but international soccer superstar Zlatan Ibrahimovic sure loves the U.S. when it comes to pool parties.

Here's Zlatan livin' it up at the Encore Beach Club in Vegas over the weekend ... chattin' up a bunch of hot chicks while flexin' out in a sleeveless shirt.

Of course, the Swedish-born superstar famously called the Team USA soccer team a "big joke" back in 2014 ... despite the fact his crappy team didn't even qualify for the World Cup that year.

By the way, Pele told TMZ Sports he LIKES the U.S. soccer team -- so, suck on that Zlatan.
