I'd pick Diego to beat Florian regardless of his performance against Penn. Sanchez has the heart of a lion and there is no quit in him. Penn technically finished Sanchez, but by doctors stoppage. I think I was fairly accurate when I picked Penn by decision.
I also think that Sanchez could put Florian on his back instead of getting outstruck and stuffed the whole time like he did against Penn. Diego has a great top game if he can hold you down, and I think he could keep Florian down. I don't see Florian getting a submission in, Diego has never been submitted in his career and even against a grappler like Marcelo Garcia, he managed to not get submitted.
I'd pick Diego by decision if this were to happen.
