Germany's defence of the World Cup started with defeat as Mexico secured a pulsating 1-0 victory in Moscow on Sunday
Hirving Lozano finished off a flowing counter-attack with a low close-range strike in the first half to put his team in command of Group F and settle a thriller at the Luzhniki Stadium
Germany have only ever lost the opening match of a World Cup once before - to Algeria in 1982 - and must now bounce back against Sweden and South Korea if they are to reach the knock-out stages
Meanwhile, there were wild celebrations from the Mexican players as they enjoyed their first ever competitive victory over Germany
Mexico's success was built upon a super first-half display
 A last-ditch tackle from Jerome Boateng was required to deny Lozano a second-minute opener and their three vibrant forwards were a constant threat on the break
Their 35th-minute goal was well deserved
 Javier Hernandez and Andres Guardado exchanged passes before finding Lozano in space on the left of the area and the PSV forward cut inside Mesut Ozil in the right-back position, took a touch and drilled low past Manuel Neuer
Toni Kroos might have levelled four minutes later, but his free-kick was pushed onto the bar by goalkeeper Guillermo Ochoa and Mexico could have extended their lead 12 minutes after half-time, but Hernandez failed to pick out Vela in a two-on-two counter-attack
Both Vela and Lozano were substituted and 39-year-old Rafael Marquez came on to appear in his fifth World Cup as Mexico adopted a more defensive approach in the final 30 minutes of the game, and Germany piled on the pressure late on
Joshua Kimmich's overhead kick, Timo Werner's far-post volley and Kroos' long-range strike tested the nerves of the Mexican supporters before substitute Mario Gomez headed wide a simple chance with two minutes to play
Julian Brandt clipped the outside of the post in the final minute of a wonderfully tense encounter, but Mexico held on for a famous win which leaves the world champions, who would likely face Brazil in the last 16 if they finish second in the group, battling to qualify and keep alive their hopes of winning back-to-back World Cups
The PSV striker was heralded as a potential World Cup breakout star before the tournament and his dynamic and positive display on the left of Mexico's front three will have earned him more admiring glances from Europe's biggest clubs
 While Javier Hernandez put in the hard yards and Carlos Vela was a willing runner throughout, Lozano provided the classy touches - and his fine finish in the first half proved to be the crucial moment of the match
 The only shame was that he was withdrawn with 30 minutes to play as Mexico adopted a more defensive approach
Germany head to Sochi for their second game of Group F and a meeting with Sweden next Saturday (7pm, UK time)
 Mexico are also in action on Saturday when they play South Korea in Rostov-on-Don at 4pm UK time
