I was about to ask OP why Haaland was not on his or her list, but when scrolled down to read other peoples comment i found this perfect list. in all honesty this is a good list and a perfect rating, and would want to see Haaland win this year Ballon D'or. Haaland is great striker and he has scores a lot of goals. Lamine yamal is the second person i am projecting to win this year Ballon D'or if Haaland doesn't win it.
Haaland been in the list is okay but winning is not really possible I mean the season he did great when they won the premier league back to back has passed and last season they barely play a good football if not in the middle or late of the season they started playing well. Assuming it was when they won the premier league back to back I would have said it is possible but this time is a not possible and the people that is on a clear stand to win is kylian Mbappe, Harry Kane and Lamine Yamal, I'm sure any of them will win.
It's posible for Haaland to win this year's ballon d'Or but the chance of him winning it is very small compared to players like kylian mbappe, Harry Kane, and lamine yamal.
As for last season you can't say Manchester City didn't perform well, because they actually did, it's just that they were not consistence in winning their matches and that was what prevented them from winning the premier League title last season which resulted in Arsenal winning it.
And just as you said in your comment, assuming it was when Manchester City won the title back to back Haaland would have been in better position to win this year's ballon d'Or, however let's see how it goes.
