Facing Messi in training is helping Hall to improve his game, even if he admits that the Argentine icon can prove impossible to stop at times. The 17-year-old, who is yet to make his competitive debut for Inter Miami, added on lining up against Messi, Sergio Busquets and Jordi Alba: “I’ve played 11v11 against them. It’s crazy. They just think faster, they play faster. It's amazing to have them on the field next to you at this young age. Messi actually played on my side [of the pitch] and was up against me. If you watch Messi's games, you see him walking around, scanning the field, then all of a sudden he checks his shoulder and then he's just gone! He moves so quick and it was hard for me to keep up. I was frustrated, even knowing he's one of the best players in the world, because I want to be able to guard him. I want to better myself and be able to defend him really well in the future.”
