Ronaldo is a very great footballer today. So the possibility of him becoming a football coach will definitely be very big. Apart from that, if Ronaldo becomes a football coach in the future, I am sure the price to bring in Ronaldo will definitely be very expensive (to train). So in this case I totally agree with @x-ray. Because if, for example, Ronaldo continues to play football until he is over 45 years old, in my opinion it is unlikely. Because, even though Ronaldo is a footballer who is very disciplined in managing his lifestyle. So he can still be very fit today. But even so, Ronaldo is a human who certainly has certain limitations. So in my opinion, it is unlikely that Ronaldo will play football until he is 48 years old.
And talk about the wider career that Ronaldo could pursue after retiring as a football player. In this context I completely agree with @arallmuus' assumption. The reason is, currently Ronaldo is like a world superstar. Maybe most people in the world already know Ronaldo. So, if, for example, Ronaldo wants to become an artist or actor after retiring from football, I don't think it will be difficult for Ronaldo to get a positive response from this. The reason is that until now Ronaldo often stars in advertisements for various products.
So in essence, both of your opinions are not wrong. Because the two assumptions you both put forward are very reasonable. However, I personally would add a little, namely don't forget that Ronaldo currently owns a company. So it is also possible that after Ronaldo retires from the world of football, he will focus on the business world.
Well Ronaldo is getting close to retirement and for a man like him who’s conquered footballs world for over a period of 10 years plus together with Messi it’s very understandable the whole speculations flying around on what Ronaldo will be doing next after football retirement. Yes most people always want to keep watching their fave after football and as such different speculations of him still being in the limelight.
A lot of his fans would think of him coming back to football after a year or two rest, probably as a coach and they believe his value will really skyrocket as a coach. Yes it’s quite possible he comes back as a coach but I guess he might not do pretty exceedingly great as a coach as we know most great footballers doesn’t succeed so well as coach and as such I think he will give that a very deep thinking before he ventures to the coaching world.
Another speculation holds Ronaldo coming back to our screen to feature in movies and I feel this is going to be more realistic than being a coach. Yes he’s going to sell out the movie with his fame and if he can act well too that will be a great plus for him and the producers of the movie that’s if he doesn’t even own the movie, Lol.
Finally, yes the thought of him going to venture into business is very very possible as you can see man has lots of investments and might just decide to chair one of his investments and keep the money coming in and yes he can become the face of the brand and you see the brand selling out quickly. So you see Ronaldo in his after football life will be able to fit into anywhere, he just needs to make the right decisions and then he’ll keep making his money from the media because of his fame.
