I dont think the result at the Bernabeu is in doubt. Real Madrid win that.
The real issues are:
1) how much Liverpool concede, because GD may well be crucial in this group. For that reason gnashers will park the bus and hope to keep it down to a single goal or two - and he has 'permission' to do that from a fanbase who expect nothing more than a hiding.
2) what happens in the other group game. If there's no winner in that game, Liverpool will be laughing their bollocks off at having their fate well within their own hands - even after two losses to Madrid. Only falling a point behind the other two teams: they'd have snatched at that before the two Madrid fixtures were faced.
There needs to be two wins in that group tonight for this to be anything like funny.
It hardly matters. Even if they get out of the group, they'll be bummed by the first decent team they play in the KO stages. And compared to Liverpool, all of the remaining CL teams are decent.
