I believe that Kopp got the turnaround with Liverpool. I was quite sure that Klopp and Liverpool might part ways after this season, but now even if they don't qualify for the Champions League, which would be bad by the way in my opinion, I think they are going to stay together and try again in the next season. The Champions League would put an end to a very complicated season, but we have to wait and see.
They are fighting and trying to achieve a spot in top four till the season ending. If the season has about 3 or 4 more matches than now, very possibly that Liverpool will beat Manchester United. However it is a big if which does not exist in reality and Liverpool have to move forwards and they must win their two remaining matches. At the same time, they have to wait for Manchester United to lose about 4 points at least in three remaining matches. Liverpool can complete their task but they have to rely too much on Manchester United.
According to my assessment based on Liverpool's current form and the upcoming games for Manchester United and Newcastle, the possibility of Liverpool finishing in the top 4th spot is still very much a possibility.
A point and two points separate Manchester United and Newcastle from Liverpool, respectively, and neither team has played their 36th game like Liverpool.
Chance for Liverpool is not too much, but too small indeed. They will need Manchester United lose 1 match, 1 draw or 2 draws in three matches in order to have same total points. If two clubs have same total points, Liverpool will have better direct statistics and goal difference than Manchester United.
Liverpool will benefit greatly in the race for the top spot if Manchester United and Newcastle lose and draw their respective matches. To accomplish that achievement against Manchester United and Newcastle would be a miracle.
Yes this is a very important condition which I don't believe will happen.
