I think it's a legit question, honestly. Yeah, it's an odd match-up but I also think it's interesting to think about whether Hagoromo, who is a literal shinobi God can match up to Tsunade in raw physical strength. And the answer is - we don't really know, but I'd wager not? I mean, the only physical feats we've seen of Hagoromo were shown in the anime and were not canon. They were quite impressive (he actually ripped a tree from the ground) but again, not canon. So, that automatically makes Tsunade the winner.

And yeah, as @Thekillman pointed out, Sakura does not possess Tsunade-level strength. She has to match up to her natural strength by utilizing chakra.
