For one thing, it's nice to be back at Tardini. This was a big game a few years ago, when Parma where pushing to be among the big teams, and they often beat us there. Serie A was pretty damn strong in the 1990s and early 2000s.
In more mundane issues, this is a yuuuge game for us. Atalanta play away to Napoli and Roma away to Inter, while Lazio should beat Chievo at home. At this point it's probably ideal if Inter beats Roma IMO. If that happens and we win, we'd take a bit of distance from Roma and Atalanta finally, and only Lazio would be at three points, but we beat them on head to head. That is also true against Roma and Atalanta, but not for Inter, so another reason to "root" for the perdenti. After this, it's just a handful of games.
Paquetá may be ready to play at least some minutes for this one. Some rumors of Zapata starting too. I didn't watch the last game, so can't comment on recent form. I understand it was more of the same, but getting that result was tremendous. I'd say at this point grinding the results it's the only thing that matters, and while that's always true, it's not as if there has been any pretense of caring about anything else this season. Just win this one.
Parma have been extremely up and down this season, with a tendency to be very poor in 2019, but they're coming off a pretty massive win at home against Genoa last time, their first win since January. They're fighting for life, so intensity should be up there.
