In episode 103 of the anime there is a *superscript* stating words to the effect of:

'Apparently, Sakura is being trained byTsunade'.

Had this been proven before, in either the manga or the anime? I know that various suggestions had been made, trying to account for Sakura's presence in the series, considering her current ineptitude.

If it is true, does anyone believe that it will bear any significance? In EP 103, Sakura almost appears to have some strength (she uproots a mast).

I await your replies.

*Edited: from subtitle, to superscript.
