The Frenchman, who has recently been linked to the top job at Bayern Munich, was snapped on a beach holiday in Qatar. And Twitter was here for it.
A noticeably ripped Wenger received a barrage of support from starstruck fans.
"Almost 3x my age and still in better shape than I've ever been," user @Patrick_JW wrote. "Wenger more fit at 70 than me at 25," another wrote.
Others were in disbelief, questioning whether the photos were real, but given there a multiple shots doing the rounds, we have it on good authority that they're 100 per cent legit.
Wenger has been out of a job for almost 2 years and has obviously spent his time away from the game keeping himself fit.
Fifty years ago, Wenger made his football debut for Mutzig. Although he didn't have an illustrious career as a player, the 70-year-old took charge of Arsenal leading them to several premiership titles. He was also responsible for the infamous "The Invincibles" squad in 2003.
If we can look half as good at age 50, we'll be pretty happy with ourselves.
