The exact same thing that happened in the previous generation Chuunin Exams, Sasuke x Rock Lee fight all over again. This is what going to happen in Boruto x Shikadai.
Boruto is bratty, cocky, arrogant, just like Sasuke was (except for the bratty part) back in the day. He will think he can beat Shikadai but Shikadai will win the fight. That's why Boruto will chase Sasuke, because he will see that he is not as strong as he thought, he will realise that he needs more training if he wants to surpass his father.
