I am not disputing their corporate governance, purely that (from my point of view) I find most of the group stage matches to be footballing mis-matches and in that sense not hugely interesting.
Of course you get the odd anomaly and upset in this respect, sport and all that. You will also get the odd clash that is intriguing to watch such as last week’s encounter in Madrid.
Last 16, knock-out stages, wheat from chaff, rutting stags, other clichés. Simply better matches in general.
If you tracked the variability of who gets through to the knockout stages against who makes the top four in the PL I would be surprised if there is much difference. If anything I would expect the knockout stages to have more volatility than the PL.
