The British record-signing assisted each and every goal as the South American stormed to a 3-0 lead, before adding to the scoreline himself with a magnificent chipped finish past opposition shot-stopper Manuel Neuer. The Germans were able to pull two goals back in the latter stages, but didn't have it in them to complete a comeback.
Playing on the right-side of Gerdado Martino's 4-2-3-1 system, the Argentine international was handed a licence to push forward and provide maximum support in attack. He fully justified his £59.7 million fee with this performance, providing a wealth of reasons for Manchester United fans to become even more excited about his arrival.
Despite his one-footedness, Di Maria proved adept on the right flank, causing considerable problems for the German defence. In this role we witnessed his ability to run with the ball, before cutting inside to shoot, or sticking wide and playing a perfectly weighted ball into the box.
No doubt Louis Van Gaal will have been licking his lips, having seen this display. Di Maria's ability on the left, or as a central midfielder has never been in dispute, but this latest international match-up will have alerted fans to his prowess on, what had previously been considered, his weaker side.
Red Devils fans will spend the evening formulating a multitude of potential systems that the 26-year-old can now excel in. It's certainly difficult to see him occupying a role in Van Gaal's current 5-3-2, considering, his attacking capabilities would be wasted if forced to play as a wing-back.
In truth, if utilised on the flanks, he'd be far more suited to a 4-3-3 set-up, or a even an adaptation of 4-4-2. Of course, he is also adept in central midfield; a role in which he thrived last term.
The prospect of Di Maria linking up with deadline day loan-signing Radamel Falcao is also sure to leave United fans salivating.
If the former-Galactico can reproduce the service we witnessed in his side's victory over Germany, the Colombian is likely to enjoy an extremely fruitful season in England. The duo could form a simply sumptuous partnership.
Amid concerns regarding the Manchester United back-four, plus a lack of balance between the attack and defence, the club's fans still have huge cause for optimism.
Despite conceding over 50 goals last season, Brendan Rodgers' Liverpool still managed a second-place finish with star players Luis Suarez and Daniel Sturridge steering the ship. If Falcao and Di Maria can have a similar impact at Old Trafford, than anything is possible.
