Everything you're unable to comprehend isn't magic. This us fairly basic stuff. Creative players tend to pass the actual football better and have more intelligence in possession than less creative players. That's how they improve their team, not to mention the goals, assists, movement etc.
Then so does literally every other great player? Casemiro is a great defensive midfielder so he offers protection to players which means they'll have more freedom, more space, more chances on the counter, etc. and his teammates have it easier, that's how it works with good players. It doesn't mean other players suddenly turn better and their shooting, their passing, their decision making will be any better. Put Neymar, Messi or Ozil in a team and suddenly everyone around them will be better... what you're claiming is magic or fantasy, not football.
Suarez hasnt been great this season despite the statistics. And even when it comes to stats didn't he just score his first CL goal of the season? It probably has to do with the player himself too of course.
Also, football is a team sport and a lot depends on the manager, the style of play, the tactics, the morale, fitness etc. All other things being equal, creative players or players who are better on the ball improve the whole. Odd that this is even being contested.
Suarez after a bad start to the season has been playing exactly like last season, losing Neymar didn't make him any worse. It didn't make Messi worse, it didn't make Alba worse, it didn't make Busquets worse, it didn't make Umtiti worse, etc.. so what happened? What's the excuse?
Great creative players improve the whole, that's not being contested. But great non-creative players improve the whole too and Salah does it aswell. Great players obviously improve teams but they don't make each individual player around them better which is what's being claimed.
The Ozil example is a poor one. He might be very creative but he's also got a dodgy mentality or low level of grit, which isn't the case with the best creative attackers on the planet (like Neymar).
So creative players with grit improve the whole, but creative players with no grit don't improve the whole?
I can give you example after example of it not happening but there will always be an excuse for when it doesn't happen so it's impossible to prove wrong. It didn't work with Neymar because Valverde came in and changed the system, it didn't work with Ozil because he has no grit, it doesn't work with Messi in Argentina because of whatever reason, it doesn't work with Hazard because of Conte's tactics, it doesn't work with De Bruyne for Belgium because of Martinez, etc... if you say something works and then find an excuse for every single time it doesn't, of course you'll be right. Pretending something is a fact and that others are stupid and unable to comprehend it does not make it a fact. Like you said, it's fairly basic stuff.
Salah has been doing what he's been doing not just with Liverpool, I saw him doing it with Egypt too just a few weeks ago. He's having success in different systems and while playing against teams with different defensive strategies. He might never score as many goals in a season, but anyone expecting this to be a one off season will be wrong.
