I can tell you that this is what every single goalkeeping coach tells their players. They make them train this particular scenario again and again and again. More and more strikers are being thought not just 1v1 composure, but to also target the weakest part. In the 1990's, making yourself bigger was the best self defense when you're all alone against an oncoming forward. Sadly a training situation is much different than a real-life situation. 80% of goalkeepers choke, Thibaut showing such tremendous confidence at a young age is a very good sign. If I'm not wrong, it was a similar situation with Messi in the World Cup. He is arrogant in the right way and its fucking brilliant.
