Legendary Spanish goalkeeper Iker Casillas has cast doubt on the United States moon landings!
Neil Armstrong and Buzz Aldrin first stepped foot on the lunar surface in 1969, meaning that 2019 will mark the 50th anniversary of that "one small step for man".
However, a number of conspiracy theorists believe that the moon landings were faked by the USA, with such evidence presented as an absence of stars in photographs and that the American flag fluttered as if caught in a breeze.
There are answers to each theory, but Casillas has now thrown his own hat into the ring, insisting that he has his own doubts.
