Sakura thinking that she has finally caught up with Naruto and Sasuke, she causes an explosion with her punch and she gets saved again by Sasuke and Naruto... LOL, irony at it's best in Naruto.
I don't think you really understand the meaning of the word "irony".
I agree about her not being as powerful as Naruto or Sasuke. But I don't think she thinks she is, she just meant she can keep up with them as a team.
That's the same thing. What the hell? Nigga you don't know what irony is.
