Your take is all way too subjective and feeds into a popularity contest mentality. Which it probably is but the justification for it isn't correct. Henderson didn't have a better season than KDB but the writers chose Henderson.I agree that KDB had a brilliant season that year, but the performance of the team isn't a function of who wins the award for best individual. A club's success is rewarded with the Premier League trophy because it signifies the team that performed the best. It doesn't by extension mean that the best performing player must have played for that team. In term of POTY, more winners have come from teams that haven't won the league than players that have. Suarez, Henry, Bale etc all won it when their team didn't win the PL because they were the most outstanding player.
In 2018/2019, VVD stood out. His defensive numbers were virtually flawless; he single handedly took a leaky Liverpool defence and made them the best defence in England. In that season, we had multiple great performers like Sterling, Bernardo, Kun, Dinho etc but our success was based on collective brilliance as opposed to Liverpool's because they would never had put up a title fight without VVD as we saw in the year prior. Us winning this domestic treble meant nothing because the award was for the best performer in the PL alone.
That's why this season it had to be KDB. He was simply THE outstanding player in the league. There was no peer and, as much as the media tried to push it with every inch they could, the players were never going to argue anyone deserved it more.
If you do it by goals or assist records being beaten or some truly significant achievement reached by a certain player(something based in fact), as I suggested then it does make a little more sense. When that's not the case though, the first port of call definitely should be to the team that was better than all the rest.
It doesn't by extension mean that the best performing player must have played for that team.
While this is true, as I said above, it should at least be the first place to look. Just to ask the question, did they have an outstanding player that made the difference? If yes, then that's your guy, if not then look elsewhere across the league. Winning the league with your team shouldn't exclude you from being considered. Claiming "this player was the most out standing" is not a reason it's a statement and normally one based on press hype. They influence so much and they have no love for City.
Liverpool's season was every bit as much of a collective as City's season was in 2018-19, so I'm not buying that argument one bit. They have two top young wing backs and a world class GK(they have formed a solid unit now), their front three all got mentions too. I can't even remember a time when Kompany even got a look-in for one of these awards and he's had some standout seasons and massive performances, same for Silva and Aguero. VVD is a great player for sure and he has improved their squad but the real reason he won it, was due the ongoing media darling treatment and their influence on the masses.
Happy to agree to disagree but I don't think this is the first season where City had the most outstanding player.
