Estonia haven't won a single official game since 18 so the outcome of this encounter seems quite an obvious to me, especially after the Czech's victory in their Nations League group. I'll go with a 2-0 win for CR - something that happened in the two previous clashes between the teams.
Considering the form of Liverpool's defence since the turn of the year, Auba and the rest of Arsenal are more than capable of harming Klopp's top-4 hopes at the Emirates.
Salah, Mane and Firmino, meanwhile, will be facing David Luiz so I think BTTS is what you need.
