This year, however, 73 points may not get us 4th. It may just be good enough for 5th. But if you would argue that it would be equally successful as the 2014/15 season where we got 5th on 64 points.
As far as the strength of the opposition is concerned, it all depends on what opposition you are referring to. In our hypothetical (and more than likely this season) example of 73 pts getting only 5th, that means that the opposition at the top half of the table is pretty strong. If that's what we want to be measured against, then I would say 73 and 5th is a better performance than 66 and 4th (the pts that got CL in the 2019/20 season).
