That’s what I think as well.
Highly unlikely that it will happen but you never know.
Napoli getting at least a draw from from Genk at home is a given.
Now, RBS beating Pool is not a given at all. But, they will be at home with nothing to lose. You never know. If it happens, then it's brilliant news for us.
Even if Pool get through (by far the most likely outcome) they have weaknesses as well. Citeh, Inter, RM, AM, Juventus, Bayern, PSG and us all have their chances against them, they are probably the best team in the world, but they can be beaten for sure. Already Salah and Firmino look seriously off-color.
Edit: According to the bookies, there is a 25% (at least) of Liverpool losing their final CL GS fixture. I will gladly take that.
