With all due respect, that is totally bullshit. There are players who are able to score goals as well as make a positive contribution to their team's overall play.
Suarez' record is partly because of the team, but also on him. His record is shocking for a player of his stature compared to literally every other relevant striker in the World.
I'll hope Suarez can quiet people up by stepping up in the CL too instead of looking like a dead fish there.
Meanwhile you can guys can talk about laymen not understanding football while adding zero to the discussion, zero argument, zero counter-arguments, zero contribution whatsoever than blind fanboyism and digging your heads in the sand.
Those 24 games are more than relevant considering it stretches from 2016 to 2019 as of right now.
But why would you start at 2016, seems arbitrary, considering his two best years in the CL were right before. That would be called cherry picking your data. Why not also tally assists? Wait I just did that using the years you picked, here is the tally, Firmino 7 Suarez 7, Griezmann 6, Aguero 5, Cavani 3, Kane 3, Lewa 2. That sure adds some different interpretation right there. In fact Luis in the CL in his career has 20 goals and 16 assists across 48 matches. His goal right is slightly down from his career rate, but his assist rate is slightly more. There just isn't much to read into, one or two big games can flip numbers, you point out Firmino but he just had a season and half (small smaple size) and I can assure you the goal and assist rates won't continue at those rates because it is out of step with his league rates (lots of games to base his rates on).
Further, I am not sure what you argument is. Somehow the CL matches football is played different, and Luis has forgotten how to play the game he has been world class for a decade at? Do you really think the intensity of a match like today, or in league vs Atletico or Real, and even at times say at Sevilla or at Bilboa or at Valencia in league at their place or later round CDR cup elimination or CDR final don't stack up to you average CL match in terms of intensity or level of footy played?
Some fans put extra wait in CL, and crazy fans suggest it is better to win a single if it because you outlast and get lucky on the way to winning a CL, over a domestic double that includes league titles that comes down to the best teams, less luck + say a domestic cup. But those are more of a causal fans (or fans of Bayern or Juve or PSG where league titles are a piece of cake compared to Spain or England) and I certainly don't think players and managers look at it this way (CL or nothing). Sir Alex isn't know as possibly the best manager in footy history for winning one CL per decade,, but giving Man U the English title record.
Atletico is a great case study. By and large they have had our number in the CL, we have had their number in league and CDR. It is not because we approach the match differently or they approach the match differently in one competition or another. The truth is we are a little better than them, but if they have their A game, and we make mistakes, or a bad call, we can lose a match or tie to them pretty easy. It is pretty much random when that has happened, twice it happened in the CL where we made mistakes and were punished. Almost opposite of Real vs Atletico. Atletico had some really bad luck in the CL where they could have easily won two, but lost one in a PK shoot out and Ramos saved Real in extra time in the other. Atletico's league and cup matches vs Real of late have largely broke for them. Which competition it happened (who wins, who loses) between these 3 teams is largely a matter of chance and not a product of one competition vs another.
