Great game. Vinicius didn't have much joy because bob didn't dive in and kept his distance and challenged at the right time.
Semedo's problem was trying to match Vinicius stride for stride and he got burned. He needed to hold up ahead of Vinicius and make him come for a worse angle
Semedo should have been more patient like Roberto who simply refused to go in for the challenge.
Roberto had the luxury to learn from Semedo's mistakes.
Semedo did NOT have a chance to learn to play Vinicius.
Roberto's tactic is OK until Vinicius can shoot better.
