Proof of Time Travel in Photo

A Grecian warrior showed up suddenly on the grounds of the World Cup championships today.
He was carrying a sword and shield, and said he had moments before been in a battle led by Alexander the Great.
Remarkably, he had during the transition from antiquity, lost his ability to speak ancient Greek.
His ability to time-travel was apparently a freak accident of having been struck by lightning during the battle, but it did not impair his ability as a warrior. He destroyed the entire stadium and left a swath of bodies in his wake.
Present whereabouts of the ancient Greek warrior are not known, but police have issued an all-points bulletin for his detainment on charges of trespassing and public nuisance.
