Ronaldo can bring more confidence to Napoli players if results are good but if results are bad, he will create more pessimistic sentiment and more pressure to Napoli coach and players.
He is different than Ibrahimovic because he cares more about himself and his personal records first. Ibrahimovic cares more about clubs he plays for. Ibrahimovic is not obsessed with personal record and personal achievements. Ibra does not create negative pressure to his team mates and his coach like Ronaldo.
Exactly. We can give a good example about this by the way.
When he was playing for Juventus and they were doing well, there wasn't any problem at all. He scored so many goals with Juventus shirt. However things started to go really bad for Juventus later on and Ronaldo also started to be very uncomfortable with being there. We all remember how he left Juventus while he was close to signing for one of the Manchester clubs.
Things are going on very well for Napoli now. Hence I assume he wouldn't complain about being a part of the substitutes there also. Because it looks like his priority is to play for a team that compete in the Champions League. Of course he can find chances in the starting eleven. But for now it is hard for him to have so many chances while Osimhen is showing a satisfying level of performance. I wonder how good Spalletti and Ronaldo would have a relationship with each other. If Spalleti is eager to accept Ronaldo in his squad then they wouldn't have as much problem as Ronaldo has with ten Hag.
