He has a lower ratio goal per game than Messi, Lewandowski, Kane or Haaland but he did indeed scored more goals than them.
Undoubtedly he has been a goal scoring machine. This gave him the status what he has right now but it also brought his downfall.
Gareth Bale in one of the podcast talked about this. He said initially Ronaldo used to fall back and work more in the deep. He was like this in ManU and first few seasons at Real Madrid. Then, he decided that he doesn't need to fall back and he can position himself better to score more goals. He wanted to win. He wanted to beat Messi and for that he wanted to score goals. So, he changed his gameplay to just focus on better position to score more goals. These are Bale words.
It worked wonderfully when he was in Real Madrid with Casemiro, Modric and Kroos in midfield.
But it also made him more dependent on others to score. Once he left Real Madrid and later Juventus, things started falling apart for the same reason and it kept on becoming worse as he grew older.
People say Portugal teammates don't pass balls like Argentina does with Messi.
Thing is Messi plays so deep that he controls the game. He influence and impact their entire momentum. His vision of how to move forward gets visible because he's there with players in the mid. And that's why every build up goes around Messi because he's there to control and execute.
Ronaldo doesn't do that. He doesn't control the momentum and build up at all. He waits for Portugal players to do that and then anticipate that they will pass him in the end just to finish and that's why we don't see the same co-ordination like in case of Argentina.
