One good example that comes to mind is Gareth Bale and Cristiano Ronaldo in the early 2010s. Both of them were incredibly quick and athletic wingers, that were scoring a lot of goals. Both were freekick specialists back then, with the exact same freekick style. Also both were both tall and strong, allowing them to be an aerial threat and useful for defensive set pieces, unlike most wingers. Many people called Bale at Spurs “a left footed Ronaldo” and when he joined Real Madrid they formed an amazing attacking trio (with Benzema), winning 4 UCL titles together.
Any other similar cases?
Musiala and Wirtz for Germany. One of them is bound to get benched for the latter. Constant rotation between them may also result in mediocre international carrers for both.
Nagelsman has now repeatedly said he wants to play them together, so I’m not sure your prediction makes any sense.
