I myself would usually use Bellerin due to his pace as in every other fifa pace has been everything when it comes to wingbacks now you need strength aswell. Kyle Walker is undeniably the best but he comes in at a hefty 35k which, when your trying to budget for a team is stupid.
Since buying Aurier there is no doubt in my mind that he will not be replaced for a very long time, he doesn't have Walker or Bellerin pace but he has enough to keep up with your regular strikers. He is 5'9 which is tall enough for a wing back but his main asset is his strength, Mbappe and Jesus get shoved off the ball all day long. His heading is also great for that of a wing back whenever there is a corner if the ball lands on his head he puts a good effort in at goal.
He costs currently 1.3k so it would be stupid to use anyone else in your team. One last point, his positioning is fantastic he rarely is not where he should be even after a run on the wing he is quick to get back to hsi usual position.
