Yes 12 points is a very difficult gap for Liverpool to reach in their remaining matches, and I think there is very little chance for Liverpool to win a UCL ticket. Also I personally not too sure that Liverpool will be consistent in their remaining matches, because their performance is still not very stable. But actually there is still a possibility for them to be in fifth position, which is currently occupied by Tottenham, and I hope the reds don't give up in the remaining games of this season for a better position.
Liverpool must win in several matches to get an additional 12 points of course with conditions like this will make it impossible to achieve easily, Liverpool will have to fight several strong teams that are difficult to beat to reach the top 5 of the standings, in the next match Liverpool will fight Chelsea are likely to win if Liverpool can work well as a team.
